77 2.7 issue
Hi guys, I have a sick 77 2.7 at my place.
Customer/friend brought it in to me, hasn't run in 11 years. Flushed the gas tank and dug into some wiring issues. There was an original issue of no spark, but I noticed that Someone had the coil hard wired as well as the WUR. After giving power to the hot side of the coil, I can get the car to run (barely). I ran it very breifly to get some EGT from the cylinders to see if I have a misfire. I have temps in the 160 range on the 1-3 bank and no temp on the 4-6 bank. Jumped cam timing?

Fuel distributor is jumping out at me. Bad/old varnished fuel gets everywhere, not just the tank.

Think I'd be doing a compression/leakdown test before inflicting ether on the poor thing.

Check the cam timing, that's where a novice would get lost.
Everything else is just torque specs... Bruce |

I am bring this thread back up....
Engine is coming out today to check cam timing and do an over all check of things... It doesnt look good. One question I do have is do they make a replacement plastic connector for the main wire harness coming off of the chassis? The one in the car was in pieces.

Never use ether on a 911 engine, you may as well try to start it by using a sledgehammer on a piston to spin the crank.

Beating a dead horse, leakdown is 80-90% on 4-5-6
