I checked the forum first to see if anyone else had done it.
One topic said he'd done it a couple years back so I read the topic and all it said was that he needed to shave the rocker cover by 3mm.
So I attempted it.
First attempt. Shaved the rockercover - started it up, started ok - but massive air leak at the manifold (I didn't have a new gasket:( ) it ran, but rough as guts!!
So today I ripped it all back off, bought a new gasket, sealed it with goo, put it all back together
Aaaaaaaand........ No dice
Tried aerostart, tried pumping it, after holding the crank for a while, it's like it builds up, almost to the point where it wants to kick, then dies.
I tried clutching it.... No dice.
Upon further inspection, the whole thermo housing (manifold) looks like it's fouling not just the top of the housing.
I'm now sitting here waiting on a mate, just so I can get home.
Im pretty sure I need to rip the prick back off again and grind all of where the thermo housing is.
Aaaaaand in the previous topic there was nothing mentioned about the EGR.
Unless he thinks all lancers sound like vw's
