We have a 1974 914 2.0 in need of an engine. The car has been sitting for 30+ years. It will run, sort of, but leaks oil like a cardboard tanker. The F.I. checks out electrically, but the engine won't accelerate. So, if we have to fool around with it, we should consider the following choices:
1. overhaul the existng engine 2. replace the engine with a rebuild from ? 3. try to resurrect the F.I. 4. just carburate it. Who has experience with overhaulers they'd share? How about "new" engine providers? I gather from some postings here that "Import World" doesn't enjoy lots of support from this group? Who else? We are looking for a stock engine or maybe a mild warming for street use. What say you, O Mighty Tribe? |

When I find these old motors, I typically pull the motor and replace all the seals.
Front and rear main seals. Push rod tube seals. Oil pressure sensor Oil cooler seals Fuel Injector seals Valve cover gaskets. Oil sump gaskets Oil temp gaskets (if so equipped) I also remove the head tin and clean all the flamable mouse nests that are in there before they catch fire. I would suggest that you do a leak down test to see how well it holds a seal...then go from there. If you want a turn key motor, McMark will do one for you...PM him. Jake Raby also does turn key motors, but those are bigger. For local shops, you need to track down Ray Mital..he is around here somewhere and he knows alot of the shops in NJ and NY Rich |

Rich, thanks a lot.
The worst of the leaks seem to be coming from the push rod seals. What makes that bad is that it drips right on to the heat exchangers and I'm afraid I'll set the whole thing on fire. Lots of smoke from the exhaust too. But it did run well and accellerate normally. I think that a rebuild is in order as this engine may only have 60K miles on it. Looked at Jake Raby's site and was pretty impressed. I'll look for Mital. Have you got any feedaback for Import World in CA? They have a bunch of engines, suspiciously cheap. The closest shop to me is Powertech in Boonton, NJ (Mike Daino) They seem like good guys. Ever dealt with them? Our biggest problem is time. We have brought this car about as far as we can with the time available, but time is hard to come by. On the time vs money scale, we are shorter of time at the present, and we'd like to get this car done! Thanks for any suggestions.
