I have a quick question. What does it mean when the i drop the oil pan and see some "muddy" colored and feeling oil? This is from a gtir motor, which hasn't ran in a few years and has been sitting in a warehouse. Could there be something wrong? or maybe just from sitting this happens?? I am starting to worry a little bit about this, but its not in the head, because i had the valve cover off and all was fine, besides a little sludge build up. I am assuming the motor wasn't taken care of very well, but definitely not beat up. To me it seems like the oil wasn't changed enough and maybe thats just what you get when you don't change your oil enough??? My next thought would be a blown headgasket, which I am praying its not??

Anybody have any ideas?

First off i already have the motor, but no there is nothing in the oil, like metal or anything it's just sludgy and thick. Now this isn't all the oil, just a little in the oil pan. Like I said though the car has been sitting for a few years and everything that was up is all at the bottom now.

I looked in the upper pan and its fine, with just again some black sludge. The oil in this motor wasn't changed very often.

Anybody else? When i bought the motor it had no intake mani on it, so couldn't some moister gotten in there that way? Also I sprayed some engine cleaner and brake clean all over too inside the intake and exhaust manifold ports. Maybe that? And it wasn't alot either just a little......

if you let oil sit in an engine for that long period of time it will sludge up and and become realy nasty. i would say the you couldnt realy tell if it was a headgasket unless you put new oil in and ran it for a couple weeks, or just pulled the head. i would say that you ok. just clean it realy good with parts cleaner, put it together put some castrol gtx(realy good anti sludge oil) in it run it for about 5-10 min, change the oil and just wait to see how it holds up. moisture, oil and time can create lots of sludge. hope this helps

Yeah, after some thinking and talking to some knowledgeable people I am going to put it in without touching the headgasket. I think from sitting without a intake mani on it for a couple of years in some nasty warehouse caused this sludge build-up???? I just can't see a car with 50,000 miles on it, built as well as this motor is having a bad head gasket. I mean I am sure it can happen, but I highly doubt it.....well we will see what happen's when it cranks over for the first time in a LONG time this weekend(fingers crossed)

Do it right the first time, or you'll be doing it often.

You've got the motor sitting there, now is the time to replace some key components. I'd replace the head gasket, headstuds, water pump, oil pump, and gaskets. Better to do it while the motor is out of the car, and before you put it in and end up having issues. A motor that's been sitting in a warehouse for 3 years probably isn't the best to just toss in a car and run.

Well I already changed the oil & water pumps, cleaned the head & oil pan. I am doing a leak down test today and if it fails then I'll do the head gasket, which I think is fine anyway. All the cleaning fluid from me cleaning the head had to go somwwhere and thats where it went.

I'll keep you all updated.....

btw why would i mess with the already very strong head studs:confused:

i could type a whole big long post explaining that your situations are very similar.

but im just gonna call you a douchebag

george posts a reply to give you some words of advice and your snotty with him? maybe thats not how you meant it but it sure as heck seems that way to me.

theres thousands of threads on gti-r swaps and everything related to it aswell as oil sample tests and if you've been a member for over a year then you should know this.

so heres a suggestion, say thankyou when someone offers advice and if you dont want to then get used to using the search button. not to many people are going to help a 30 year old unappreciative jerk

If I came off as snotty I apoligize. I meant no disrespect and listen to everything I'm told. How many things have u told me and I listened? I did a leakdown test and everything was fine, changed both the oil and water pumps, etc......so where did I come off as a jerk, which btw I take ALOT of offense to.

Ok, I am home now and see that your talking about B13GFB4. How in the hell did I come off as snotty or duchebag or whatever other derogatory word you used to describe me???? All I was saying was that he was basically telling me things i already knew(searched for) and or was already told. How is that being a jerk?? I went over all the things he said and was just saying that his situation and mine were different, because of the reasons stated above thats all. I think you got a little carried away with all the name calling bro. I always take advice from anybody who is willing to give it including yourself who has helped me out tremendously with this swap.

Again if i came off like that to george (B13GFB4) I apologize and didn't mean it that way. I hope we can move on from this, because I am not a jerk or douchebag and think that was way out of line. I mean if I said he was stupid or something of that nature then fine i would deserve to be called a jerk, but what I did was harmless and just said that his situation and mine were not the same again becuase i already did everything he said in his thread.

and btw searching is overrated because it takes me over a hour to eventually find something that helps.
