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 for the reply.
No, have drained the oil 3 times with new filter every time, and have used an oil flush with one oil change too.

I’d say the oil pressure is low cause the tensioner wasn’t tight, that is were the oil has lost its pressure.

Wow quite a lot then. Was the oil light flickering before the chain was done? Why did you change the chain?

Plumb an oil pressure gauge into the switch port and verify whether it is a genuine low pressure.
You may be very lucky and find it is only a switch problem.
