VL_Turbo

Installed the catch can today, Hopefully that should de pressurise the crank a bit. I've read on the internet some people do use JB weld. cannot find a spare rocker cover locally in south easter suburbs 😭

Even though it's not pressurised still won't work?

Update, tightening the rocker cover bolts and went a bit too tight and cracked the rocker cover near the bolt next to spark plug 4. can I JB weld it or put some sealant and put it back on or do I need a new rocker cover? Any help would be appreciated 🤦🏽

Just a thought, could the ARP head bolts cause the issue? Maybe need retightening?

Ho All, Have a small issue with my VLT. maybe someone could help. driving normal is good no problems, but when I press the accelerator ( every 1 out of 10) I hear like a bang noise ( similar to an intercooler pipe popping off noise), I then notice oil from the drivers side block but if you drive normally it doesn't happen.... Any idea what that noise could be and where it's coming from? )only on boost) 5psi. you can see on the pic the inlet manifold gasket is wet from oil. Also noticed oil in the spark plug holes, but only happens on boost, drive normally I don't have the oil leak issue. What can make a "intercooler like popping off noise" and then leak oil on drivers side(only on boost) - see attached pic. thanks

Thanks to everyone on this forum for your help. I'm stoked. Car is getting tuned on will inform with the results. very unusual thing happening, wondering where that loud noise is coming from the drivers side, oil should not be on the intake manifold gasket as per the pic above

Update.... car is alive!! After 4 flushes of oil no more contamination. Car is up and running and all is good.

Went the 226f / 274 cam

I bought Penrite flush oil. Went online and I was told it can harm the engine? this is my Nitto 1.2mm multi layer steel head gasket, can only go on one way right?

Can I put oil flush in it to remove the contaminated oil?

Done compression test came up as follows 1- 111psi, 2- 115, 3-119, 4- 120, 5-120, 6- 115 done coolant pressure test and not leaking or losing coolant and definitely not losing coolant via turbo drain. Puzzled is understatement atm.😳

Runt too much boost on a hot day with nearly 300,000ks on the motor. Old head gasket was worn out. with the head bolts I followed the Gregory's manual. Used head stud and lube on the head studs. will take rocker cover off and recheck the torque, I believe it was 97nm for head studs. no idea about what you mean to seal head studs to water jackets?

Forgot to mention, took all spark plugs out and they were all the same (black in color) should I try a leak down test or coolant pressure test? Thanks
