Screwed up H22

[arcadiacb7]

ok the h22 in my prelude is fucked up. The head had this white grease all in it and a little moisture around. The white grease/sludge was really thick, so i'm not sure if it is moisture. The motor makes an ass load of blow-by, has a ticking that is best heard right above the freeze plug on cylinder 3 on the block and barely heard on the head or anywhere else. I pulled the oil filter last night and barely anything came out of it but the oil wasn't too bad. The oil pressure light is always on but when the motor was ran with the valve cover off it had plenty of oil pouring down on the cams. and if it really didn't have good oil pressure then the bottom end would be smoked by now after the previous owner running it and driving it. And my time from diagnostic failure. So what do you guys think. Oh and the bottom end was rebuilt by da9b16 and i bought it off of him. I put new rods and mains in it, oil pump, and oil pressure sender after i blew it up once. OH and compression test is
cyl 1- 175
cyl 2- 165
cyl 3- 165
cyl 4- 160

so what do you guys think

Compression test is pretty close together its fine. 5-10psi is within range. Anyway oil pressure light is on either check the switch and such plus oil levels. And that muck you said I had some in my engine and cleaned out most of it. Bought some shitty normal oil, drove it around for 500 miles, drained it, refilled with shitty oil drove it for 1g, drained it then went to synthetic. Reason? To clean the motor.

but what was that white sludge stuff he's talking about? was it from moisture getting in somehow?

[NAiL05]

I dunno it was sludgy mine also. It was around the oil pickup area and some around my cams. I think when they wash the motors maybe some goes in I dont know. Firsts thing me and my buddy did was take out the oil pan. Thats when we noticed it. He took a screwdrivver and scraped most of the stuff out the oil pickup out while i clean the oil pan. At first we thought it was a bad motor but comp tested we got 215 across the board. I would think its either some sort of additive or engine cleaning agent they put in. I recall overseas they have this clear oil cleaner shit you can dump into the oil, run for like 15min, then drain and refill with normal oil. That would be the only logical thing that would explain the kinda sludgy stuff. Could be another additive they put in so insides of motors dont dry out dunno.

hmmm should i be concerned about this in my H > ?

I think I need to check this out , I dont want some sludge making my motor start acting funny ...

agreed.

compression test was with 10% of each other so it is fine.
id try and get all that sludge out.

[arcadiacb7]

well the sludge is out. And so is the head. The exhaust cam journals are fucking wasted and the cylinders look like bare aluminum. The pistons feel like there are no rings on them because they slop around in the cylinders very easily. I think the noise was a bad wrist pin. I still can't figure out where the sludge was coming from. I think maybe the oil cooler where the filter goes on may have had some damage.

While the motor was still running I pulled the valve cover off and clean all the white sludge off and reinstalled it. After running the motor for 15mins it was covered in all that shit again. I was hoping to still have a good head but now the ex journals are fucked. But i still have a good intake cam and valves and lifters. woo fucking hoo. I have my h23 bottom end assembled. I used h23 crank and rods with h22 pistons. Now i just need a new h22 head. I have new cams also. So look out for me a cheap head with cam caps that just needs the cams put in.

White sludge is water in the oil. You should've changed your oil while you had the head off to clean...

[arcadiacb7]

well my head is fucked, kinda. The cam journals on the exhaust cam are worn really bad and all scarred up. I can get it fixed by a friend for a hundred bucks but i really don't want to wait a month for him to get it done. I just want a head to bolt on to my h23 bottom end. But if it comes down to it then thats what i'm gonna have to do. Anybody heard of the oil cooler on the back of the block going bad? And causing coolant to leak into the oil?

I'd say that the $100 you'd spend on having your head fixed is cheaper than buying a new one.

price at shop:
pressure test = 55
valve job = 185
surface = 55

cleaning fees = 5

thats over 300 dollars, you can probably get a bare head for under 200 granted it might not be in best condition as a new or rebuilt one but if you need something that works, sand the deck and lap the valves in.

That's not what he said a friend could do it for in his last post.

[wed3k]

i didnt read that, i wonder what exactly his friend is fixing though.

[rudy1980]

the sludge is diffinetly (sp) water in the oil, probably from a blown head gasket, check your radiator its probably in there too.
