Blown headgasket maybe? Maybe damaged valve springs too? A compression test is in order.

maxam

Didn't know it was a built motor. Was it built for high rpms. Like stated above time to run some test and go from there.

Thats terrible man, I would have learned to shift perfectly and a garbage car not a turbo charged one. Hope things work out for you.

If water is mixed with oil than it's the head gasket that blowned, the other possible issue is that the block might be cracked but I would put a 2$ on the head gasket. My guess is that if the block was crack something else would have probably blown like a piston or a rod but there would be visible sign. Good luck, and buy a stronger head gasket, and dont shift till red line give yourself a chance to learn how to shift and save your engine specially on a boosted one.

Rev limiter (on the next engine) for the win.

maxam

ok here are the signs .

1. engine running smooth but not starting

2. water coming out from y pipe and down pipe

3. water smell when I opened the oil cap

I think if it's the block , the engine would not turns smooth .

today I ordered new cometic gaskits on the express mail DHL . I will try to finsh it quickley.

maxam

ok if you train your self on stock maxima for example .

http://www.youtube.com/watch?v=NBbfFDZAB6Y

you will shift like this and may be better . this is stock 99 maxima . it is just like a toy . in this max 0-60km in 6 seconds . pu l sh t . 60-150km in 10 seconds ???? . pu l sh t .

but how would you shift like this guy in this crazy maxima ????

http://www.youtube.com/watch?v=97GBvu2g-X8

look how RPMs goes very fast . look how the car pushing you . look how it accelerate

one mistake might kill you or couse a dezaster. here where would you concentrate ? shifting ? trafic ? Crowd ? gauges in your car ? or the car you are racing with ?

ok here are the signs .

1. engine running smooth but not starting

today I ordered new cometic gaskits on the express mail DHL . I will try to finish it quickly.



sorry for the bad words ....

Perhaps it would be best to NOT drive like a child, and if racing is something you must do, do it at the track.

maxam

ok if we dont have a track in Saudi Arabia , where should we go ?

and I DONT DRIVE LIKE A CHILD , BUT I DONT HAVE RACING EXPERIENCE !!

If water is coming out of the engine, stop trying to turn on the car, even if it idles smoothly. Its broken, now your goal is to take it apart and fix it. Cometics HG dosnt mean your safe, even if you have a $500 head gasket, and you over rev while in boost in rpm's that you havent even tuned for, the HG will fail. Take off the heads, inspect for cracks on the block, new gasket, and see if its ok.

maxam

did you know that it was running like nothing happend ?

drain the oil and check if theres coolant in it , sounds like a blown H/G

pull the spark plugs out to check them , do a compression test and a leak down test ..

maxam

I will not touch it until the new HG comes . couse everything is clear . Blown HG , the block is safe , heads need to be checked , all i need is to be patient until the new HG arrive .

so you did or did not do anything to diagnose the problem prior to just ordering parts?

maxam

no my friend . everything is clear . I opend the oil cap and I found that there is water not even mixed with the oil yet . other thing as i sayed befor I took my car back to home after what happend driving it . it was running like nothing happend .

All this are sings of blowen HG . Am I worng ?

You won't know until you take it apart, you might have cracks in the block. You need to check it out, if everything was fine, it never would of acted funny to begin with.

mywhitewolf

or AT-LEAST do a compression test on the engine.

maxam

hello guys

I took my car to the workshop today as they Scheduled it to start all over .

they started to check it to figur out the problem.

they opened the radiator and fill it with water than they left it open

than they started running the engine . at the frist run the water came out from the radiator like a fountain .

they told me that I have blown HGs .

I told them to check everything on it . crank , block, heads ,and,,,,,,,,,,

but I have Question . is the oil pump still work or should I replace it ? couse it is newly built.

Get a Rev up oil pump, which handles higher rpms.

maxam

Nealoc187

iTrader: (23)

maxam

I'm going for the Z350's one , wich is easier to find .


but i have an other question. what will happen if I use bigger boor size Head gazkit ?

maxam

here are some pics

maxam

hey bad news

we found that the cylinder need to be replaced . becouse of the piston line ( where the pistons moving ) ware un even. that means the heads will not fit in some places on the cylinder surface . so I am gonna start agine with new good cylinder , taking out my pistons and reface the heads .

t6378tp

iTrader: (69)

it didn't cause any damage to the cylinder wall

maxam

no the cylinder walls is not damaged at all . but from the beginning the cylinder surfece was not even . and I found that the cranck shaft have some rust on it so I knew that the engine was mixing oil with water from the frist time that I started the engine but I was surprised that I dont have heat problems and i chenged the oil every month and I did not find any bad oil .
but some times I fill in the radiator with almost half a cup of water .

any way Im now searching for good cylinder. I found 3.5 from an altima 05 but I dont think of bueing it .
