Thanx for everyones posts, I have not done anything to the motor except clean out the exhaust valves with just a wire brush and sucking the dust with a shop vac. Eric: Where would I begin to look for another motor? Any place u would recommend to look for motors? I live in California close to Sacramento. I will try nd do a leak down test as well as a compression test. This motor does have a lot of miles on it that sucky thing is that I had just done a clutch replacement on it. It was running fine and even passed smog but right after I seafoamed it, it started smoking more than usual. I am currently using Mobil 1 10w-30 oil weight and it burns it still, the car runs and all and i believe i am getting 30mpg so this is just too weird. Usually when i first start the car it revs up to like 1500 and stays there a while maybe till it gets warm then drops down to about 600-800rpm range and when I drive around and come to a stop the motor revs normal id say at around 500-750rpm but there are times where the rpms drop super low to the point where the car almost shuts off but doesnt. Well this is my project car just wasnt looking to be adding that much money into it. I do have a z6 head but i am looking for a D16z6 complete swap but if i could find a cheap engine that runs and whether its reman or rebuilt is fine as long as it doesnt completely empty out my pockets. Will take me time to do leak down and comp test becuz i dont have tools but hey im not in a hurry as I have another vehicle to drive to work n back. Well please let me know asap where possibly I could find reliable reman/rebuilt/used engines. thank you guys.

yea but thing is i dont have the money for a engine rebuild right now. I bought a d16z6 vtec head, and I am currently talking to someone who has a complete d16z6 swap including the tranny for 300. and he claims it runs which is good bcuz i could just swap it then work on the d15b and when thats complete swap it into my car so i could work on my d16z6 but well see where it goes, i may as well buy a gasket/seal kit from ebay and changed the valve stem seals myself clean out the outlets and by removing the head i could take a better look at the pistons and would be able to post pics to get some advice and id be able to clean the top of those pistons off as well. Heres another question, the head from my motor is a PM3-1 which is a 1990 Si head, if I get a gasket set or at least the new valve stem seals will a gasket set from a 92-95 work with this head? The head looks exactly the same so do the internals but just wondering if anyone really knows these motors to give me an answer? If I take of the head how can I check if I have worn piston rings? Anyone with good pics of worn piston rings from looking at the block please post link, i dont plan to take the pistons completely out so thats why im requesting pics from the top of the block while the pistons are still in there, bcuz i may just take the head to a machine shop or just remove head along with valve train and degrease the head then clean with brake cleaner not sure if ill do that to the valve train but i also wana clean out the valves and replace all seals.

How do i check if its fuel or oil? When I got the car it wasnt smoking or anything. I used some cleaners and even seafoamed it. then after i sea foamed it, it started smoking more. but damn if its worn piston rings too then have to do a complete rebuild but no worries cuz im investing in a z6 swap so if anything i can rebuild that and just swap. But if someone could please answer my first question in this post please and thankyou for the replies….

Well I cant do a DOHC on a d15b but I might end up just looking for a head at picknpull. I dont think its worth it to take it to a machine shop for the reason that im not gona build anything, id rather if anything pull the head off and remove the valve train, de-grease the naked head wash thoroughly as well as the valve train and intake/exhaust ports and again was thoroughly, lube everything up with a bit of oil, replace all gaskets and seals, clean up valves and put everything back together and I should be good with a nearly new head. So here’s a question relating back to the pics above, I’m more of a technical person so id would like to know what causes all the gunk nd grime? i understand that its “bad” but what other then stem seals, and head having a ton of miles could cause that?

Yea I know as soon as I took off the manifold. All the gaskets on the valve cover were changed at the same time. As far as the o rings, which ones are you talking about specifically because the valve train also has o ring down under and those I have yet to replace. As mentioned maybe im better off finding a head at picknpull save me time and money from cleaning this head. I am currently not driving this car because I am driving my other car so I have time but gotta wait for $$ to come in. But what I might do is clean out all that burnt oil by taking chunks off with a scrape trying carefully to not let pieces fall, ill use a vacuum while doing so as to prevent pieces from falling in, spray brake cleaner as well as maybe some sea foam or fuel inject cleaner into the valves but will do research before I do. Any recommendations?

Alright guys so here are pics beginning with the 1st valve outlet from the left.
1st from left (notice how above the first valve it seems to be wet)

[IMG]http://i589.photobucket.com/albums/ss331/209KINGOFCALI/4thvalvefromleft_zpsabf4bc8e.jpg[/IMG]I was thinking if indeed I have to replace the valve stem seals is it more worth it to go to picknpull and find a good head and just pull it off so basically a swap. Ive seen some clean heads almost looked like they have been cleaned at the machine shop so theres no oil burnt on the valve train. Well let me know what you guys think. The current valve cover gasket on my motor has about 4,000 miles on it, may still have warranty on it. One last question why is it so important to replace the gasket on the manifold since I took it off?

the head itself could be cracked right there which could cause it to leak? Ill take off the exhaust mani tomorrow and post pics. But thanx so far for the info.
