Hello,
Here is my problem.
I changed the timing chain and tensioner and about 2/3 weeks later the oil light started to flicker on idle when warm. I changed the sensor but didn’t fix it. I replaced the oil pump and it’s still the same. I fitted an external oil pressure gauge to test the pressure all the time. This showed that I had 30psi on idle when cold but when warmed up the oil pressure drops to about 1-2 psi. On normal driving it appeared to have oil pressure in the high revs and vtec worked fine. I done some research and fingers were pointing to the crank shell Clearances. So I replaced them with the standard ones after inspecting the crank and seeing theirs no damage/scoring. Part of the top layer of the shells had worn slightly but nothing major. Done all this and it’s still the same. (Banging head against the wall) now I thought bugger it pull the motor out and have a good inspection. My thoughts were that maybe some sealent from the timing chain when I was scraping the old stuff off had fallen into the oil and maybe blocked a gallery or something. But it seems ok. Now it’s completely stripped the only problem I found along the way was, the tensioner had come loose. the cam cover had stopped the bolts coming out any further. Now I was wondering if this could have effected the oil pressure problem?
Or if you think something else maybe the problem?
Thanks
