Hey guys.
I'm thinking its a head gasket... not to sure here is what I've noticed. When i first start the car and let it warm up, once its warm and i floor it my buddies say white smoke comes out. once its been a while I've been driving around it barely smokes white , to not even any. the car does not over heat.
i did see some coolant slowing coming down from the side of the exhaust manifold (while i was changing my alternator). but cannot find the source. i would like some advice from the people who have more experience of course. don't want to change a head gasket and all other gaskets needed to get there if that's not the problem. Also i do not have to add coolant regularly. have had the car for 2-3weeks now and its all good for fluids.
Thanks a lot
Jules

Yeah, the external leak won't be related to it getting into the cylinders.
If it's not overheating, and you're not losing coolant, that's enough proof that there isn't a problem.
To me this sounds like valve seals. Do you go through much oil? Check if it's actually oil. Idle the car and warm it up, then give it some gas.
It could be fuel - do a boost leak test. Also, the car will run more rich before it's fully warmed up (and I mean more than just a few minutes).

k i got some more info guys. first of all it smokes white ALOT. Like seafoam lol Okay i have a couple pics and a video. this is what i found. i stoped the car and it was smoking from under the hood. so i open it up and its oil that fell on the back tube of the 02 housing ( if u know what i mean ) so i drive my wife to town. I come back do the same thing. i open the hood and well its dry there.... for now. then i rev the engine ( white smoke out the tail pipe.) and i see oil AGAIN on the 02 housing. and now its spreading down towards the alternator. i cannot see it dripping. Oh and my oil fittings on my turbo ahve no oil on or around them here are some pics and video Video http://s283.photobucket.com/albums/kk289/aCx85/?action=view¤t=MOV03066.flv

ya that in the proccess Rob ordered stuff, should be in today or next week. i know its not fuel... its oil or coolant. but its hard to say under the hood its oil i believe unless coolant can make sh!t that nasty , think and greasy , smoke like that. ( id have to find out both the smells ) the white smoke im not sure. from where its leaking your thinking exhaust? as in my exhaust gasket? any house pass under the exhaust manifold ?i can take more pics if needed / Videos so my best bet would be full head gasket set ? tri layer?

Yes, reservoir is working.
It may be leaking where the water pipe meets the water pump. The pipe is between the block and the exhaust manifold, the connection is under the belts.
Leak down test probably wont help you yet. You ruled out the head gasket already. The only other things a leak down could tell you is a burned valve or leaking seals.
Coolant smells sweet when its burning.

sounds like the cylinder head is warped.
white smoke is most often burnt coolant. your cooling system, does it have pressure when full? I would no longer drive that vehicle until it is repaired.
the head will need resurfacing. A multilayer gasket will require the deck of the block to be machined. Meaning the engine will need to come out. Not necessary. how i check if it has pressure when full?

how did i rule out the head gasket? You did a compression test. Only one cylinder lower then the rest, fixed by a small amount of oil tells me you just have some worn rings. If you had 1 or more low readings that was not resolved by oil, then I would start to worry about the head gasket.

A warped head is the last thing you will want to conclude.

some technician have a tool that has an attachment that resembles the rad cap. this tool will give you a pressure reading.
usually when the system is pressurized, after shutting the car off, and letting it sit for a while, you can CAREFULLY ( hot coolant can cause serious burns) open the rad cap with a towel or rag SLOWLY to hear the pressure hiss out.
This pressure raises the boiling point of the coolant.
This will probably not happen for you. It seems like the coolant is entering the combustion chamber though that cylinder with low compression, assuming the results were accurate.
you already seem to have all the tell tale signs of a blown gasket. Loss of power? I'm not sure where that oil you mentioned is coming from, it may or may not be related. Do you have oil pressure? as in my gauge in the car? what should it read? around where? the one next to the boost gauge ?

Very true. You could also check the oil for coolant mixing into it if you do suspect a blown head gasket.

k guys here is the video. it smokes out of the manifold and when i rev it there bubbles around the manifold , on the top side cause thats what i can see. can it be as simply as only the exhaust manifold? could i be losing coolant by there? ill be cleaning the engine bay later with engine degreaser ( which my buddy says is amazing ) and a hose. with all the nasty gunk gone i should be able to see something.

okay ! So Rod this is the situation. I just bought the car as a project car. My DD is a 02 Mazda Protege5. Its not over heating or anything like that so if its not a Head gasket what would you change. Like I said before I want to have fun. I plan doing a 6 bolt swap, but since this engine is mostly functional I want to drive it til it dies. I wanna mod it like if everything was good. Once engines blows I will swap a 6 bolt ( hopefully after the summer). What would you change, gasket wise? if thats the situation like your saying. Turbo doesnt have any oil on it, other then the 02 housing. I know im losing power with these situations, but am I losing ALOT? Was going to get a head gasket set. but if I dont need the head gasket. then the job will be ALOT easier
