Bought this car for a few hundred, was running well. Drove it home about 350km's.
Next time i cold started it, it was running rough, like 1 or 2 cylinders weren't firing.
I also noticed it was losing coolant and that there was oil deposits in the radiator, kinda thick like greese (not the usual mayo)
I replaced the spark-plugs, 2 of the coils, DFI Module and leads.
Then i replaced the lower inlet manifold gasket and put new filter baskets/o-rings in the injectors while i was there. Both water ports had the mayo in them so the gasket was obviously stuffed.
It was still running rough so i assumed it was losing compression in a cylinder or two.
So I replaced the head gaskets/bolts. Used the pushrods in the same positions but didn't set lash on the rockers. The head gaskets weren't visibly blown.
There was heaps of sludge in the heads which i cleaned out.
I noticed when replacing the fuel rail, the injectors didn't line up properly, so a couple are at a little bit of a weird angle.
All the vacuum hoses, EGR hose, Electrical plugs are connected.
Just wondering what you guys think the problem could be, it's running rough like a couple cylinders aren't firing, not just at idle, but with acceleration as well, the engine has done 350,000km's.
The only things i can think of is an injector or 2 is electronically stuffed (unlikely because the engine was running ok until it was cold). Stuck or stuffed lifters. Not sure.
Any help would be greatly appreciated.
Here's pics of the inlet manifold goop and a ton of goop left on both rocker covers
