Hi All!
I bought a 1984 RRC 4-Door classic with the 3.5l engine with twin SU carbs in Nov. I got it super cheap as the engine needed new headgaskets. I took everything apart, replaced the cam, lifters, timing chain. I resealed the water pump and oil pump and new gaskets everywhere. I (stupidly?) bought tin headgaskets instead of composite but as I got a pair of heads from ebay within spec (got these checked) for less than what a skim&check would cost here in Sweden I thought it would be ok. The car has been running well for a few weeks, always starts but I've been having trouble with the cooling system not always building pressure and the temp gauge 'dropping' to zero unless I open up the expansion tank cap to sort of release the pressure (I assumed it was airlock.)
It's gradually been smoking more and more (especially during idle and when cold). However yesterday it was basically a locomotive and noticed the coolant had stopped being clear and was now a much dirtier looking colour. It was basically a jacuzzi in the expansion tank.
I feel like it's an open and shut case of headgaskets, but I just wanted to double check with you experts! I could definitely do a composite head gasket swap in a matter of hours at this stage, but just want to double check before I take the plunge on new gaskets, + oil and coolant.
It could be a cracked block but that wouldn't explain why it's only starting to smoke lately ? Mind you I haven't drive more than 500km. Any tips would be greatly appreciated.
