I bought this 1986 IROC 305TPI/Auto a month ago from a member here, said it ran rough at start but after warmed up was fine. Anyway, trying to fix the cold start and due maintenance....I have found I have issues aside from the previous owner lying about the car.

Some members here receommended changing the CTS to stop the rough cold starts. During this change I thought while at it I might as well put a new radiator/hoses/thermostat etc. I removed the rad cap and see oil in the water.

I replaced everything, fired up the car and still runs like crap. It was late so I went to bed. Next evening after work I pulled the #1 spark plug and its wet with something....#3 plug same thing, switch to other side and #2 plug looks same.

Thoughts?....intake gasket?

 

Sounds like a bad head gasket

 

I agree, headgasket.

 

do you have a vacuum gauage and compression tester?

 

one more thing, please tell me this problem isn't with a vehicle which was listed for $8500???

If it is, and the known problems were discussed with full disclosure then so be it. If there was perhaps misunderstanding, contact the prior owner and discuss his participation in seeking remedy (via cash)

 

Either way if its the intake or the head gasket intake has too come off dont know the! Whole history on the car can only asume its old
