Hi guys,
I have been chasing an oil leak and a minor coolant leak for some time.
Having redone all turbo fittings/washers and lines (found a minor coolant leak on line to turbo), fixed oil leak at camshaft position sensor and even retorqued the cylinder head (got ARP studs), I am still seeing oil on the garage floor this morning, and a hint of coolant [headbang]
Oil seems to be collecting on top of the cross-member on the intake side of the engine. Coolant is a tiny drop, occasionally, on the floor.
Top of the engine is clean and the only clue I can see is there is some oil around the filter housing -not from the housing itself, but from where it attaches.
I see no coolant however and if I just feel around (for lack of visuals) I don't get any coolant on my fingers from around there.
Thinking I might have an oil leak from the oil filter housing assembly or from some component on top of it. That assembly has just 3 years on it (rebuilt engine).
I recall there's a metal element on top of it (can't see it now), which I did not replace at time of rebuild.
So questions: is this a likely source of my issues? And can I get to it without pulling the intake manifold (would hate to redo the injector seals again)?
Thanks
