The time has come, car is leaking oil from rocker cover gasket however thought id do it all.
I cant seem to find a DIY for Crankcase-ventilation pipes? Does the complete intake manifold need to come out? Or can it be done without?
Torque settings for rocker cover gaskets and timing cover gaskets?
Help would be greatly appreciated. Doing this all this weekend. Fingers crossed.
thanks

 

If you are meaning valve cover by rocker than the torgue values are 89in-lb for long bolts and 133 in lb for cap nuts
same for taming covers. You do not need to remove the intake to change vent pipes. You have to remove them anyway when replacing valve cover gaskets.

 

for some reason i was under the impression there was 3 vent pipes, one of each valve cover and then one that goes under the intake manifold? not sure what that pipes for cant find it on real-oem? like a hard plastic shiny pipe

 

Are you referring to the old design pipe that came in one piece?




Or you are referring to the secondary air y-hose that goes under the IM (#1 on the diagram)?

 

Yeah diagram 2 the secondary, is this a common leaking problem? Does the manifold need to come out for this? Im trying to fix a leak which I can't find which is causing me cold start idle issues

 

To replace those pipes you need to remove the manifold. When I had my manifold off I examined those pipes and it seams pritty good condition as the where made with solid plastic for heat resistant. and I do not think they may get cracked. But if you decide to replace them and remove manifold you also need new gaskets for manifold.

 

The y-hose can fail. Most likely if it's cracked, you will get an "increased emission" error. Also, you might hear a "jet" sound.

I don't know whether it can really cause rough idle at cold starts. But see if the rough idle disappears when the air pump shuts off (and secondary air valves close). If it does, then this may very well be the problem.

 

I took a quick videos this morning, you will notice the engine almost like stops and starts running rough then normal after 30secs, anybody experienced this?
