Hi all,
1991 Range Rover with 173,000 miles. I posted awhile back about how it wouldn't pass smog, and cylinder #1 had low compression. (Original link down below)
Tore the engine down and found that the left head gasket had completely blown out, and decided to overhaul the top end.
Over the course of the last month, I've replaced both cylinder heads (brand new), head gaskets (and all other top end gaskets), water pump, thermostat, oil temperature sensor, oil pressure sensor, timing chain, radiator fan, and replaced all of the coolant hoses. Spent a while priming the engine, but the engine oil idiot light turned off after 3 tries.
Went to turn the key, and everything spun to life! It was shocking how easily she turned over.
There are two things that are preventing me from finally being done with this project and enjoying my Range Rover though:
1. After starting the engine, I couldn't see any indication that oil was flowing. My friend and I reasoned that since the oil filter, oil pump housing, and oil pan all quickly rose in temperature after the engine started, it was a sign that there is oil flow. Looking through the engine oil fill hole into the valvetrain though, the inside of the cylinder head was bone dry for a while before we saw any oil in there, and even then it was just a bit.
2. Engine temperature rose rapidly - a short drive around the block brought her close to red. Top radiator hose is hot, but not scalding to touch. I'm thinking it's either the thermostat or an issue with the radiator - I'll test this out later today
My greater concern is that the oil flow is restricted, and is directly related to why the engine is overheating. Anyone have issues like this before?
Also, since the head gasket blew out on cylinder #1 it's likely it blew because of a cooling system issue. So maybe it's the radiator? Has anyone ever had a RRC radiator cored?
Thanks
