Ummm 7M's have lifters. What do you think the shim sits on? A lifter. We have mechanical lifters in our engines, not hydraulic.

You ran it low on oil now it ticks/knocks. While it was low on oil you had major metal to metal contact and now the bearings are worn out of spec.

Perhaps in the most litteral sence ,the TSRM calls it a lifter ,but I'd just call that a bushing. In any case ,we agree a dry top end lead to premature wear. I got a refurbished head on ebay for $450 that came with everything except camshaft oil seals. With the increased open areas around the moving parts the oil has less restriction and hence lower pressure.

So basicly the only way to fix this is to rebuild my head?

For starters you would want to get it apart and measure everything to see just what state it's in. Keep in mind though ,it will seriously hurt your resale if it's in a million pieces. You have to decide at this point if you want to take the hit selling it cheap with potential head problems or if you want to follow the route of repair and hang onto it. Not a fast ,simple ,or cheap task ahead.

I have read and heard that if you change the oil and put an additive in it that could possibly fix it. Is this true? Because if it is I will try anything that could possibly keep me from having to tear it all apart again but I don't want to waste my money on oil if it wont help.

You may try some lucas oil additive, or some engine restore. EH
ATF in an empty tank filled up with premium will lubricate all of that stuff in the efi. That may help you narrow it down.

Well I have decided to rebuild it. Its nice owning the fastest car of all my friends... and the ladies love it . Seeing as how i have already done the head gasket before I think im just going to pull the engine and do it outside the car.

Has anyone pulled one of these before, leaving the tranny in the car? Because I have big hands and that was my biggest problem before was fitting around shit.

Also I won't have to have the head milled again would I?
