Problems with Schrick rocker cover?

4 posts in this topic

Now then.

Has anyone had problems with a schrick rocker cover on a G60?

I recently fitted one to my rallye, just been for a 'spirited' drive today, it started sounding rough, plumes of blue smoke from the exhaust... pulled over, oil everywhere, found to be coming from the throttle body boost return, all boost hoses full of oil.

First thought was charger oil seals failed (had that before!) Topped oil back up, nursed it 15 miles or so home, smoke/oil seemed to be clearing.. oil level still the same when I got home.. hmm

So i started looking into it, I have the breather going back to charger, this was full of oil. Removed the breather off the rocker cover and held it at high revs, after about 30 seconds oil started spitting out of the breather on the schrick cover? 

I am under the impression now that the charger is fine, and oil is coming down the breather at high revs into the charger. Never had that problem with the standard cover?

Anyone else had this problem with a schrick rocker cover?

So, to follow this up it does seem to be breathing a bit  heavy, I put the original rocker cover on and all good.. for a bit.

Gave it a blast down the motorway all of a sudden same again, spat all its oil out of the breather.. and engine sounding dog rough too.. crap.

Managed to crawl the 5 miles home, using 10 litres of oil in the process.. ha. Now breathing much worse, running pretty much on 3 cylinders.

Pulled the plugs, bits of melted aluminium on plug four.. I now suspect its melted piston four, causing blowby and excessive breathing, pushing oil up into the rocker cover.

So to concur, probably not problem with the schrick cover, just a melted piston!

So, I guess this proves the leakdown test results...

 

No. 2 showed as 50-60% leakage.. slightly melted..

No. 3 showed as 10-20% leakage, in good order..

No. 4 showed as 95-100% leakage, melted to buggery..

And No. 1 showed as 70-80% leakage, pretty melted too..

Guess its a rebuild then!
