Hi there. Thank you for your videos. I am wondering if a failure on this seal would cause oil leaking on the AC compressor, and eventually to the ground. I have some leaks coming from the turbo area. Trying to figure out if the oil feed and return lines are the problem or if it may be this seal. Thanks
@alphadevyatАй бұрын
@@yamaccandan1 it could be. Easy to examine the seal and replace. I use a thin bead of Hylomar sealant on it. Top turbo feed line could be a culprit too. Drains leak rarely. But I suppose with age anything will need attention. If you have a larger leak it could be the valve cover gasket. It’s a maintenance item. If you want to be preventive you should do it at about 100k miles or 150k km.

@@superplayerunknown729 I would assume that the reason you were removing the return line is to remove an injector or a few. If so, you would need to bleed the fuel system by running a bleed function in ISTA that will activate the LPFP and bleed the rail. So your car should start but the return line will see fuel pressure in it, not huge but if a nipple is broken you will see fuel dripping from it. Also your injectors will not work very well as they need that backpressure to operate properly. Best is to replace the return line. Not difficult but you gotta watch a nipple it connects to on the return feed and get a proper clamp.

Holds vacuum - confirmed wastegate holds vacuum and actuates/ moves correctly - confirmed all sov's and ev actuators work - confirmed vacuum accumulator box holds vacuum - confirmed vacuum pump works, no leaks, pulls 30" vacuum pressure.

It was completely removed. It used to t-off from the vaccum feed line to the egr and toward the accumulator box. All the vacuum hoses have been replaced with silicone and now it just runs from the feed line to the pressure coverters / accuumulator. The delete was performed about a year ago by an indy.. everything has been fine until about a month ago. I did notice that the pressure converter that is next to the motor mount EV on the drive side under the intake manifold goes to the front near where the EGR cooler used to be and goes under the passenger side engine and connects to what I think is the AGR? I connected a pump and the line isn't pulling a vacuum while on idle.. not sure if isn't even still needed with the delete and all.. I'm stumped🤦♂️🤷♂️
