where is the pressure relief valve and what does it look like? Is there a way to test it?
the pipe coming from the intake pipe goes to what I'm led to believe to be an oil separator it has a pipe connected to bottom which comes from the oil sump at bottom of engine. The other pipe that goes to cam cover as nothing along it and just connects to the cam cover? I've had the cam cover off and where the pipe connects to the cover it doesn't look like air can get through there? All you can see inside the cover is 3 small bolt heads that keeps the housing the pipe goes connected to the cam cover?
There isn't anything on the cam cover? ould it be anywhere else?
There is nothing in any pipes and where pipe goes into cam cover there is no valve it just free flows air? I think the hissing I here when switch engine off comes from fuel filter
my engine doesn't look anything like that? It hasn't been that long since fuel filter was changed and it starts almost immediately but as soon as you touch accelerator it starts spewing oil out the top of turbo where the intercooler goes, without the intercooler on the oil hits the bonnet
I haven't tried it with filler cap off . There is no pipes that run through the intercooler? It just basically sits on top of the turbo at 1 side and the inlet manifold on other. I thought the crankcase might be pressurizing cos of stuff I've read online that's why I was looking for pcv valve. There isn't any pipe work after turbo it bolts straight onto outtake manifold with intake on front of turbo and exhaust down pipe at back. The only pipes on turbo are oil pipes, 1 to the bottom which I think feeds oil in and 1 on top that goes to oil filter , there's 1 rubber hose that comes from intake before the turbo and joins what I think is an oil separator which sits ontop of crankcase breather? Then another hose comes from the oil separator to the cam cover. There's some kind of spring loaded valve on oil filter housing that's bolted to engine block but I've noticed it has the same kind of thing on the other side above starter motor where oil sensor/switch is and it looks like 2 spring loaded valves on there? I'm on phone at moment but I'll take some pictures and try to send them
