Hi guys,

About 20,000km ago I purchased a 96 4.6 on a bit of a whim. In that time I've grown very fond of the old bus and its now time to give him a little love.

It has always had what I presumed to be a lifter noise. A few weeks back it developed a rough idle, which I traced to the left bank. Low compression in one cylinder. Removing the oil filler it became evident the noise was compression leaking into the valley, rather than lifter noise.

Heads off - a chunk of missing gasket, but liners seem to be sitting nicely. Cam showing wear.

Right head off - liners sitting nicely, but a crack running down a quarter the length of a liner. As there were no related symptoms, I'm going to pretend I didn't see it, put the engine together, and source another block to rebuild ready for later.

There seems to be some confusion as to what gaskets to use. I have always used Elring in German stuff, and have never had issues. A specialist recommends against them (torque required to get a seal contributes to block cracking/liners shifting), and suggests a softer gasket, I believe American in origin, but I can't remember the name. I remember using shim gaskets back in my P6 days!

The universal verdict seems to be to use studs.

As for the cam - there seems to be a large number of suppliers selling new "OEM" cams with part number ERR5250 for a very reasonable price, like around a hundred bucks. This seems too good to be true. Is there any feedback relating to these cams? What about the head gasket issue?


Thanks!
Davide

I do the heads on these all the time, I only ever use elring head gaskets, the arp vs stretch bolts is a long going saga,, I put it down to personal choice. Head gaskets blowing into the valley is quite a common thing on the Rover v8 engine. As for the crack, are you 100% it was a crack,, if it is, you've most probably got limited time till it gives up..

Thanks for the input. I've never had an issue with elring gaskets in a wide variety of engine designs, but I suppose every engine has its quirks. On another forum Durapro gaskets were highly recommended, which surprised me, as I'd always presumed them to be mediocre aussie aftermarket stuff.


I'm quite sure its a crack, but I'm not a position to pull the engine presently, and since there were no symptoms, it'll just have to plod along for hopefully another year (10,000km) while I source another block to rebuild with top hat liners.


have you had any experience with those cheap new "OEM" cams?
