I need to do a plenum pull to redo rocker cover gaskets as it seems i have an oil leak on the pass side, (burning oil smoke coming up from battery side) I cant see any oil lower down so i think its oil leaking from the rocker cover and burning off on the manifold.

 

I have already done EGR, AIV deletes and water bypass, Can anyone suggest anything else worth doing while the plenum is off??

 

Im thinking I change the oil feed lines to the tubs while im at it as then thats another future possible prob replaced.

 

I know I need the following but anything else I need

 

1x Idle control valve at rear of plenum, as mines not working.

1x idle control valve gasket

1x plenum to intake gasket

 

Thanks Craig

Check your pcv valves, while the plenums off, give them a good soak in carb cleaner or replace if the ball valve doesnt move smoothly.

also check the post by Jeff about the connector from the PCV to the rocker covers... that could be the issue.... would give the same symptoms...

Cheers guys its a fair bit of oil, at first i thought it was sump but cant see that being the case as I wouldnt have the steam, so I think it may be the rocker covers leaking and it driiping down the back onto exhausts and then onto the flat area on the sump and leaking down.

I had the same problem with mine before i changed the engine, it was leaking onto the manifold and used to smell awful, especially after booting it lol.

yeah thats what mines doing and with it being cold you see teh smoke coming up from the back of the bonnet, it seems to be pretty bad at the min, as im getting alot of oil sitting on the flat part of the sump if that makes sense? i cant see any oil froming from the sump gasket so it must be coming from further up, so im thinking rocker covers is a good place to start.

ive got the same problem only drops on boost i think. seems to be alotta crap roun dthe pcv tubes so i think il change the piping that connects the valves.

How much are you getting fella, as one night after a pretty heavy drive, i stuck some card board under the engine to see how much was coming out and i easily had a good tablesoon of oil over the cardboard, problem is because its blown back over the sump and gearbox its hard to find the exact location of the leak, so gonna start at the rocker covers and work my way down.

i drve my car about 50 t0 100 miles each week i dont ever nee dto top up tahts how little. im talking drops. but annoyingly if im booting it about it lands on the tubs and burns off then when im sat still for prolongued amounts of time pretty embrassing at say a level crossing in summer.... :/ like you im going top work from the top down. its really ahrd to trace but i get quite a bit roiund the oil filter tree.

does sound like we have the same issue, gonna try and tackle mine over the next few weeks, ill put some picks up, may do a write up if one hasnt already been done.

I think my rear cam cover are leaking only on the driver side i think it running down the back of the engine and dripping on the oil filter not much it doesnt leak on the floor yet.Can you get to the bolts to nip the covers up dont fancey a plenuem pull is there a gasket there or is it sealant thanks ,

Unfortunately not mate.... Inside 2 (intake) are a rubber gasket, Outside 2 (exhaust) are liquid gasket, and buy good stuff, or you'll only end up doing it again...
