Jag 6 Cylinder Project

I really need to stay off Facebook marketplace as I've now picked up another distraction....

In mid September while perusing FB during my lunch break, I decided to key in Coventry Climax as sometimes things pop up (found an FWA cylinder and block a few years ago that I've now donated to the brother of a coworker who has an Elite).  Lo and behold a firepump popped up in the search.  Upon closer inspection of the photos it appeared to have a proper FWA/B/E cylinder head casting.  I asked the seller if he could send me a photo of the manifold side of the block, and to my surprise it was an FWB block casting.  After looking at the photos, telling the GF about it, and having one too many pints, I bought it sight unseen (other than the photos).  

The motor was on Vancouver Island, so required a ferry trip.  We headed over to pick it up, in hopes it would fit in the back of dear old dads Dodge Journey (it was a bit too big to fit in my Jag XF).  After much struggling we managed to get the pump assembly up on the lip of the tailgate area, but quickly found out that the pump cage was about 2 inches too tall to fit.  We then elected to call it a day, and figure out another way to get it back to Vancouver.  We had another trip to Scotland that was going to delay getting back across the Salish Sea.  By coincidence my cousin was over on the island while we were touring Islay, and he, single-handedly, managed to get it in the back of his pickup and deliver it to the garage.  

Which brings the little story up to this past weekend, Saturday saw me pull the motor and pump out of the cradle:

The pump was removed:

I then started to investigate what I really had.  I pulled the head and it turns out it is a genuine FWB pump, meaning it has the 3" bore and 3.15" stroke (1460 cc).  It also, by some strange reason, had a proper rear main seal:

The earlier pump that I converted years ago had a scroll on the crank acting as a seal, and the proper automotive type Climaxes had a piston ring type seal.  Both are now typically changed out for a lip seal after machining the crank.  

Next, the oil pan was removed, and what came out of the pan can only really be described as a chocolate milkshake.  I was fearing the worse for the bottom end, I though for sure it would be totally corroded.  Luckily, that wasn't the case, everything looked fairly decent:

The best bit was next, it turns out the crankshaft is a forged EN24 crank.  I couldn't believe my luck, this means the motor is very useable as a conversion.  The earlier pumps had cast cranks which work fine for engine speeds below 6k rpm, above that things go bang.

I did have a good look at the cylinder head (but forgot to take photos), it appears to be useable in stock form other than swapping out the valve springs.  The valves are the correct automotive sizes, and it looks like it has the smaller combustion chambers.  

After all that excitement it was loosely put back together and parked beside the other projects:

It will require a full tear down, new pistons sourced (the current ones have soup bowls for piston crowns), a new crank pulley, new water pump pulley, a steel timing gear, and some minor machining done for the oil filter take off.  But, the big question is what should I do with it?  Make a coffee table with it?  Send an RFQ to the laser cutting company I used to get a quote on either a Lotus 7 or 11 chassis cut?  Sell it?  I already have way too many projects on the go, and really shouldn't have bought it, but the asking price was less than two nights out at the pub.  

Well, I decided to spend some of the Toj budget on the Climax.  Both dear old dad and the GF suggested getting parts for it sooner than later.  I now have a set of very lightly used Omega pistons, a refurbished FWA oil pump, a steel timing gear, and pulleys for the crank and waterpump.

The supplier I use for Climax bits has also sent some instructions on how to tap into the oil gallery so that I can use a proper oil filter.  I'll post some photo's of that once I get around to completely stripping the motor.

Excellent choice of distraction. Well played.

Tojiero made some Climax powered cars. They were lighter.....One I saw a few years back here on the east coast was not much smaller than your Jag project either. May have picture....

Bill, 

Yes,  I've seen a few photos of the Climax powered Tojeiros, and I think the Toj chassis that's currently for sale in the UK is a Climax one.   It looks a bit "lighter" than the Jag powered one that's in Elgin. Though dear old dad is now trying to convince me to build another Eleven.  I'm tempted to send the chassis drawing off to the laser cutters to see what it will cost.   Somewhere in my pile of drawings I also have a scan of a body line drawing of the S2 body minus the bonnet (it even has F Costin's signature on it).

I would do a Lola Mk1 if I had the ambition. I don't! Having done some Climax internal work FWE specifically, I would make it run well and sell. Great engine for their time, but the Jag project will be far more road functional. Also I found the photos of the car I remember, and it had a fiberglas Falcon body, much like some Mk1 Elvas. Not real elegant, but better than many....

Well, it happened again..... I went onto FB market place while having a pint and bought another motor:

This one is a 4.2L from a Jag 420.  I have no idea when I'll find time to take it apart / rebuild it, but it was such a good deal that I couldn't pass it up.  

Other than that, not a lot has been happening in the garage, the Elan hasn't really had much attention, and the Toj hasn't moved an inch.  But, I did figure out that the double cardan joint that I ordered from RA was incorrect.  I found a Neapco version of the same part number somewhat closer to home, and it turned out the Spicer one I had received was boxed incorrectly.  The Neapco version fits the tunnel I welded to the chassis, so everything should now line up.

In reply to RoddyMac17 :

At least it was another size U joint in the box. I received a reverse idler (I think) in a box for a Bosch ignition pickup assembly. Also from RA. I think someone previously scammed them, the gear was used. It fit the box a little tight, but it felt heavy before I opened it. Find another 4.2 jag engine cheap and you can use them for table legs, keep your Jag focus on the little one!

I've bought myself a new toy! Instead of buying a larger TV, I've bought myself a 48" box and pan brake with 16 ga capacity:

I figured that I'll be needing to bend a number of panels in the near future, and my little 30" bench top brake was definitely not up to the task.  The new one wasn't terribly expensive, but it is bleeding heavy.  I'll be making a stand for it in the near future, but for the time being it's been shoved to the side of the garage.

Other than that, not much has been happening.  I am hoping to spend more time in the garage this month with it being "dry January", which might extend to "dry February" depending on how things go.

Dry January!! You aren't even 200 miles north of me 20 miles east of Seattle. It's been wet just about every day since the new year started. I hope the dry January was just in jest. 

Kind of wondering how come you didn't make it left hand steering? More of a original copy with a few easier modern pieces upgrade? Still bet that will be a blast to cruise around Vancouver B.C.

Brad,

Dry January is self imposed prohibition in hopes of shedding a few lbs and putting some extra beer tokens in the car budget(s).

As for RHD instead of LHD, I wanted to keep the build somewhat of a copy of the original.  One of my pet peeves is seeing very nice replicas/tributes/copies of cars with the steering wheel on the wrong side (Jag C/D types in LHD for example).  I know it would make it much easier to drive, but it's just not my thing.  

Ok that makes sense. I'm a non drinker so I didn't think of the dry as not drinking. 

I can see the original context being a good thing from that aspect. Not all that difficult to drive still.

Happy birthday to you. 

Congratulations.

Happy birthday to you. 

Congratulations. 

Happy birthday to you. 

Congratulations. 

Now, get back on that Toj!!!

I managed to get some time in the garage over the past two weekends.  One weekend was spent making a stand for the brake:

Getting the brake onto the stand took a bit of force, and some non-worksafe procedures as the engine hoist didn't quite work out as planned.  In any case, it's on the stand and I've tested it out.  It bends much better than the cheapy 30" benchtop one that I picked up years ago.  I still have to figure out bend allowances and how to properly lay out parts, but I dont think that should take too long to sort.

I've also started on taking some offcuts from the 4x8 sheets of aluminium and turning them into "things".  I wanted to try out creating a compound curve with the sandbag/panel beaters bag, nylon hammer, and wheel.  I managed to come up with this (please excuse the mess) :

It still needs some trimming and the rest of the tunnel has yet to be fabricated, but I'm pleased with the results.  

Other than that, another small order from Send Cut Send arrived, and this was part of it:

My friend, who gave me the 2.4L motor, told me the story of the "Stutzenberg" and that one of the builders, Hugh Porter, made up a tag for the "Mellow Bellow Muffler Co." and stuck it to the exhaust on the Stutz.  I thought it was humourous and decided to re-use/borrow the idea as I'll be fabricating a muffler for the Toj (due to space limitations).  The tag I had laser cut will get plug welded onto it, though I'm sure no one will really see it.

Interestingly, the "Stutzenberg" popped up on BaT last week, though sometime between when it left Vancouver and ended up in the UK the Duesenberg motor was removed and replaced with a Stutz.

Nice vintage wall art in the garage.

Does the "quickly gone together" include the hours spend on the puter drafting up the chassis in Solidworks ( or whatever you use)?

Not that I follow my own advice, but the option of using CAD and  manufacturing to build hobby cars is a game-changer; even if you dont actually build the thing, you can realize a lot of neat stuff digitally that but for a E36 M3-ton of hours and $$$ COULD be realized.

Curious if you ran any finite element analysis on the chassis? Assuming this chassis mimics the original, curious what the original would show?

Pete

Pete,

There's been quite a lot of time spent modelling the chassis, but what else am I supposed to do at lunch?  Be healthy and go for a walk or a run?  All of the drafting/modelling was done in AutoCAD, I wish I had a Solidworks license. But as my day job consists of using ACAD and Civil3d, AutoCAD was the cheaper option.  The really neat thing about modelling the whole chassis and portions of the body in 3d is finding interferences, then looking at the photo's of the real car and noting where they worked around the interferences. Not to mention how nice it is to get laser cut brackets, rather than spend hours cutting, grinding, and bending a bracket, then finding out it doesn't fit.  The only downside is the cost of getting things cut. I'm sure I could have bought a plasma table with what I've spent. But as space is limited in the garage, it's sort of out of the question.  

As for FEA, I haven't run any kind of analysis on the chassis.  I'm guessing my interpretation of the chassis is slightly stiffer than the original, as I've added a bit more triangulation in the engine bay area. 

In reply to RoddyMac17 :

Funny, but when I arrived at my old job 20 years ago, I was an AutoCad user and was under the impression that it was obsolete, so made all of my  staff learn SolidWorks. They all got real good with it and I was quite proud of them. I continued doing my drawing needs with what they called "Etch a sketch" 2 D  AutoCad drawings.

I did not know that AutoCad was still around much less that they were doing 3D work.
