I picked up a few things at the Skip Barber auction. Two of their open wheel parts cars, "the last Ricardo" transmission, and a couple pallets of open wheel parts were going to be donor parts for a MOD class autocross car. Once I got them home and looked things over it was decided that because the roller chassis was in such good shape it would be so much easier/cheaper to rebuild it. Here's how things are going so far.
The chassis had a motor, but the chassis was very oily. A quick glance thru the side of the engine block and out the other side confirmed the source of the oil.
The red tag on the transmission identified it as "the last ricardo" and said it had knocking from differential. I've cleaned it up and will investigate it's problems after I get engine running. I've looked online and other than corporate headquarters I have found very little info on Ricardo gearboxes other than they aquired Gemini (who may have been the original manfacturer of this trans). If anybody has some knowledge on this trans please share
I was able to trade some parts for another skippy engine. I don't know if it runs but it came from a wrecked chassis. I'm assuming it runs because cars that don't run are much harder to wreck. I would have just gotten a junkyard neon engine but the rods destroyed the custom low profile oil pan as they made their exit. As I was cleaning up the new engine I discovered there were no spark plugs. I swapped in the plugs from the blown engine to fill the holes so I could pressure wash it. Once clean I removed plugs so I wouldn't forget to remove them and hydraulic the engine when I cranked it. I squirted in some wd40 in the plugs holes just in case there was some rust on the rings and figured what didn't get blown out on the initial cranks without plugs would eventually burn off from combustion. I changed the oil, looked like used oil, no foam, no water, no chunks or shinny bits.
I finally got the engine and trans together and in the chassis. Everything is connected for the engine to run. The chassis didn't have an ECU but one of my parts pallets had a few engine harness, one was attached to an ECU, another was brand new. I tried to remove the ECU from the older crusty harness but the screw wouldn't back out. I think the nut inside the ECU is spinning. I cleaned up the old harness and installed it with the ECU. One of the chassis even had a battery with it and it held a charge (enough to crank it a few times) so I connected it. I hear fuel pump whirring, a good sign. I disconnected fuel pump and pushed starter button. And something happened. I wasn't expecting anything to happen. I was sure it wasn't going to crank but it did. Remember when I took out the spark plugs? Good thing I did. It spewed a bunch of nasty rust water out of the number 2 hole. I wiped things up and congratulated myself for thinking ahead. As I was coming back from trash can I looked up an noticed this.
Looks chunky. That ceiling is 14 ft high and it went splat hard enough for chunks to stick.
So after cranking for a while, it was time for fuel and spark plugs. First plug in spark plugs and check spark. All sparking but dimmer than I would like but the cranking speed has slowed down a bit. Right now I'm just looking to verify if engine has everything it needs to start. I put my thumb over spark plug holes and all seem to squeeze some air. Two of three parts are present.
Let's add some fuel and reconnect pump. No leaks, that's a good start. Fuel pressure in rail, even better. Grab the fire extinguisher it's time to really try to start this thing. Everything needed is there, it should fire. Nope.
I pulled the plugs and they didn't smell like fuel. check spark again and it's still good, better with jump box. Time to check injectors. All four had a positive voltage at plug. Cylinders 1,3 and 4 would only pulse once on cranking and I had to cycle the power to be able to get a successful pulse on the next injector. C.ylinder 2 was pulsing as it should. It was same with only one injector unplugged or with all injectors unplugged.
I suspect something is telling the ECU to no send fuel or the ECU is fried. I tried to plug my cheap OBDII scanner into the plug but it wouldn't even come on. There are only four wires to the car side of the OBDII connector, maybe scanner needs its own power source. If it has a battery in it it might be dead. I will have to try on suburban later.
If it is an ECU issue my concern is retrieving the custom standalone tune from this ECU and getting it into a new one. I WILL need help with this
So that's where I am so far. The parts list is growing. In addition to the previously gearbox repair I need to find or make these parts:
- body -have hull, and left side pod. Have a source to mold left side pod. Need nose
- CV joints- have about 15 axle shafts and no CV joints. source identified, about $60 each plus boots
- rear sway bar and mounts
- gearbox mounts - top and left side
- shifter cable bracket-most/later cars used hewland gearbox with shifter on top, ricardo shifter is on bottom
- wings - can run without for a while and unless I go to spec series (unlikely, who's?) Mostly for track days and I think SCCA BM just limits area so I'm not tied to originals
In GRM I've seen that Bertil Roos is taking over these cars. If anybody has contacts there, the parts pallets I purchased at the auction contained some boxes of new production parts for the cars in quantities that I can never use. I'm interested in trading....
