Hi all
Recently replaced head gaskets on our 1989 3.5 EFi which was steaming like the Queen Mary and losing water like no tomorrow. Water loss is now negligible but I am still having a few problems:
When the engine is started from cold it is a bit 'clunky' under load - feels like a misfire sort of thing - and there is a bit of steam from the exhaust (sometimes a fair bit to be honest) after about 60 seconds of driving the steam goes away and the engine runs smoothly - whether the two are connected I do not know.
I asked about this prior to doing the head gaskets as I felt it was a separate problem - as a result of that I have already replaced plugs, leads, dizzy cap and rotor arm, capacitor, amplifier was new in August as was the coil. I can find no vacuum leaks or loose connections in the LPG system.
It does this whether on LPG or petrol.
The heads were not skimmed (oops) but I did check them with a straight edge and light/feeler gauges.
Frankly I'm not bothered too much about a lumpy start that clears itself but what I am wondering is whether I have a crack in the head (or a warp or something) that, when cold, allows some coolant into a cylinder, once the engine starts to warm something expands and seals the hole/crack/whatever?
Any ideas/suggestions??
