    Got the oil pressure sensor replaced, it was definitely leaking. Iím sure I have more leaks, the passenger side control arm is basically soaked with oil. It could be the timing cover, or maybe crank seal? More to look into

    Got a few more things checked off the list...new oil filter, valve cover gaskets, serpentine belt/tensioner/idler pulley. The hose going from the oil trap to the valve cover is broken, so I bought the entire kit from eEuroparts that includes the trap and all hoses; but for the life of me I canít get the hoses disconnected from the trap! I feel like I need a third set of hands to pull as Iím squeezing those grey tabs. I considered just cutting the hoses off so I can slide the trap out the bottom, but thatís kind of a point of no return solution. The two bolts holding the trap to the block are already out, intake bracket is out, I feel like Iíve given myself the best chance of success but Iíve so far failed miserably. If anyone has any suggestions, Iím all ears!

    Haven't tackled that one either. My '99 doesn't have the oil trap set-up but is one of the things I was gonna hit this spring.

    Ended up cutting all the hoses close to the trap (I have all new ones) and then was able to get it out. What a bear...it looks like the older traps are much smaller than the one on my Ď06. I thought Iíd be able to get it out under the car, but the exhaust would probably have to be dropped to get it out that way. I read somewhere that a guy got it out the top, towards the right side between the intake and belt tensioner, so thatís where I finally got it to come out. Took quite a bit of cursing and scratched up hands/arms, however!

    Finished up installing the hoses last night. My god, what a pain. That whole design is the spawn of the devil, I swear. I spent about an hour and a half wrestling with the hose from the oil trap to the valve cover...only to finally discover that there was an extra o-ring stuck in there that was preventing it from seating all the way. After I figured that one out it went a LITTLE better, but still a huge pain. Glad thatís all over! Just gotta replace the vacuum lines with silicone now, but that should be a cake walk compared to that disaster.

    Still dealing with a pretty significant oil leak...starting to aggravate me. Finished doing front main seal replacement as well as oil pump o-ring...was pretty easy other than wrestling with that giant circlip. Wiped the right side of the motor down and took it for a quick drive; came back and it was already dripping! My next step is drop the oil pan and reseal (Iíd like to check the condition of the oil pickup screen anyways). Iíve never had a vehicle make this big of a mess in the driveway/garage, so Iíd like to get it resolved ASAP!

    I would have a good look at the timing cover gasket and crank shaft oil seal, as you mentioned at post 11. I am sure that you have confirmed that what you are seeing is actually engine oil? The level is going down and you are having to top it up regularly. Are you sure it isn't coming from the oil cooler or associated pipework?

    Crank shaft oil seal=front main seal, correct? Or are we talking about two different things? It is a real possibility it could still be timing cover gasket, I was just replacing what I thought were the most common causes. Itís definitely engine oil, level does drop; location of leak could certainly be anything that you mentioned! It just is heavily biased to the right side of the engine. Lower control arm, and even the fender liner have become covered in oil over time.

    I would hesitate to call the crank shaft oil seal the front main seal simply because it isn't at the front with a transverse engine but we are probably talking the same thing.

    If oil is going forwards I would definitely look at the oil cooler.

    Replaced timing chain tensioner seal(s) last night, looked like it was leaking from there as well. Guess Iíll just keep knocking stuff off the list! Iím second guessing dropping the oil pan, however...on second glance it really looked pretty darn clean. Since it seems to be leaking on the right side, I guess the last main culprit is probably the timing cover. I just canít seem to pinpoint the start of the leak; Iíll have to clean everything really well and start over at this point.
