The ultimate tappet thread

[Wayne]

I have not read the whole thread but have you checked your oil pressure.

read the thread fella

its good if you want to kill an hour or two

and yep he has

Something else worth checking, bit of a long shot but is your camshaft 100% a hydraulic version.

Hi
How do you tell the difference ?

I should hope so.

Yes I know yours is hydraulic but has the cam ever been changed.

Not whilst I've had the car, but when I take it off again tommorow, *sigh*, I'll look for stamps/markings. But it did used to be quiet - this has only really started tapping constantly since the refurb, before it was very intermittent.

Well, I drained a litre of oil, filled her up with a litre of the finest Dex II ECP would sell, then had to figure out how to drive ~100 miles. So I filled the tank and just started driving, ended up in Blackpool, so 140 mile round trip and a respectable 44mpg later, I've parked her up for the night ready for an oil change tommorow.

I'll be removing the sump, cleaning the pickup, replacing all the tappets, putting a new filter and oil in and praying to every diety known to man. If anyone else has any reccomendations for me, post before 12pm tommorow and I'll check it.

Reference the oil pick up pipe, punch a hole in the center of the gauze, should help you build pressure quicker,

I drained the oil, pulled the filter and the oil was (albiet black) clean and free from metal filings, swarf etc. I dropped the sump and cleaned it out, the pickup was barely dirty, but I dorpped it out and cleaned it too. I took the cam out, measured the lobes - all even, pulled out the old tappets and put in the new ones.

I put on a new oil filter, and filled it with 4.5l of fresh 10w40. Spun the starter for 25s without the fuel pump on to prime the engine. Started it up, no oil pressure warnings, so thats good, it runs fine, no hesitance. Let it run for 15 minutes whilst I tidied my tools away, and guess what its exactly the same.

I've lost all hope.

The only thing I can think and it is a long shot but has someone fitted a hydraulic head on a early block or maybe just maybe the head gasket is wrong and blocking a oil way.

I see in your other posts that you have measured oil pressure at the head have you checked it at the block which would confirm the above.
