Just rebuilt my 4y and have the oil pump getting to the oil filter but not seeing it get to the rockers after idling for 2 minutes, so out of fear of breaking something I stopped running the motor. How long should I be letting it run before it gets to the rockers? The oil pressure light goes off on the dash

On my 4y it takes about 5 to 10 seconds after I start the engine before lifters stop making any noise

Did you replace the lifters? OEM? Is there perhaps not a blockage in the oil gallery somewhere?

If the rockers themselves are getting oil (messy, but you can check by running at idle with the tappet cover off), then you're not likely to cause any damage. Some vehicles chatter on the lifters for quite a while before quieting down but 2 mins is actually quite long.

Was this on first start up? Maybe the lifters haven't "filled" yet. :think:

Ok so it was the very first start up, I decided to wait it out and run to see what happens 🙈, it's the Chevy lifters that I bought new. Ended up taking about 5 minutes to eventually go quiet. Felt like a make or break situation

Cool! What happens with the first start in the morning?

Normally if there is sufficient oil pressure for the light on the dash to go wrong you should be ok. Unless an oil channel is blocked.

Ok so I started driving the vehicle and the tappets started getting noisy again and there is not much oil coming through the rockers , I'm wondering, I went for chev lifters for chev 350, is there possibly a wrong chev lifter to buy? The shape and size was roughly the same

Sven the lifters size should not be roughly the same.It must be 100% the same. The high revving chev lifters I used part nr is HYT04-04.I bought mine from Masterparts in Kenilworth Tel 021 657 5757.Compare your partnr with mine to see if you have got the same ones.

Did you check that all the pushrods seats properly on the rockers?

So the lifters I got from alert engine parts was Mahle clevite 213-1638, the guy said it's for the chev 350 hydraulic lifters. I contacted masterparts to see if they have stock of the HYT04-04, if they do I will just get them as I think this is my problem. I guess not all lifters are equal. Ha ha.

One question, do I need to replace the head gasket if I only ran the motor for 20 minutes?

Why do you want to take of the head? You can remove the lifters without removing the head

Didn't think about it to be honest, replaced them when I rebuilt the motor so havnt explored the idea of removing them through the valve cover but I guess it makes sense

You could have a little problem taking them out with the head still on, and that would be if the gasket is protruding around the sleeve edge somewhere (can happen with some pirate gaskets). One would have to carefully cut away any protrusions if there are. :winkx:

Sven you will have to remove the rocker shaft. A strong magnet works very well to remove the lifters or a piece of wire with the a hook bend at the end.
