ok today i started the max it runs fine it was in a slumber after i ported the heads, replaced the gaskets, replaced the exaustmanifold studs(50 buxs from nissan for 12 w/50% disc. bout 3.80 a piece!!!!) now when i start it i let ir run and then it goes for a while and i get smoke coming from the exaust manifolds both front and rear it gets to the o2 sensor and im guessing thats what is making the engine die down a bit not as if its dieing but just a slow down i havent taken it out for a drive yet fearing that it will shutoff at a light or sometin, anyone kno what this smoke is and where it is coming from(White not blue) i dont think that it can be a coolant leak because i used sealant and torked down the heads to spec (22lbs, loosen, 44 lbs) i dunno but i hope someone can help me so i can take it to get it smogged by this week and then ill be on the road thanks...

 

did you use any kind of sealant on the gaskets?

 

yeah

it was leaking before the sealant thats why i used it that permatex copper stuff

 

is the smoke coming from out of the exhaust or is it just something burning off the surface of the manifolds?

 

Have you checked for coolant loss or any other leaks around the motor? Leaky valve covers?

 

when i took off the manifolds the second time it looked like it hd coolant in the manifold covers as for leakt head covers i dont think so....

 

did you use a new intake manifold gasket?

 

Big-E Dog, that thing is sharp ! I have a 1987 black Max that's gonna have to have a new power steering pressure hose and I was wondering if you had replaced yours ?

Are they difficult to replace and are any special tools needed ?

The space sure looks tight.

I don't mean to hijack your thread but it sounds like you know your way around the Max V-6 engine bay !

Thanks !

 

it took me 6 hours in my 85 on jackstands with a 24mm sosket use a breaker bar and a 6-10 inch extension when i did mins i didnt have a breaker bar that mofoin nut is TIGHT as he11 then take off the other nut make sure the car is cold or youll burn your self MANY times cuz itsd sooo tight back there abd dont loose those crush washers or better yet use newonoes i didnt and i had no leaks also refil up with atf fluid dexron 3 w/mercon (same stuff in an auto tranny)

E-money thanks !

Ya scared me a little but I gotta do it and I appreciate the good tips !

Thank ya, Sir !

 

youlll be fine


and there was coolant loss before i drained 2 1/3 gallons then i re drained it and i got 1 and 2/3 coolant it was oozin somewhere and oozin a lot but i removed the intake plentium down to the heads and now im gonna replace the gaskets there (the old ones are new) with a new set and hope for the best...

 

interesting, is that because it is a little thicker than the power steering fluid or what is the reasoning behind that? Well in any case, I am still using regular old power steering fluid and the power steering doesn't leak and feels nice and smooth (may be due to good maintenance and prior replacement of everything by old owner)

 

Actually my 2nd gen all of a sudden just started smoking really bad for like a week last summer. I lost a few nights sleep cause I thought my baby was done for. There were oil drips on the front exhaust manifold heat shield but I couldnt locate the source. It turns out my valve cover somehow was not tight. Tourqued it down and nary a problem since

 

well with further tests and research its not the head cover but the head itsself its leaking antifreeze into the combustion chamber through the runners. the vg30e has 2xx,xxx miles and needs to be retired but i will keep the body...... ne one in the sandiego area have a engine crane that i can borrow in like a week?

 

Didn't you just port the heads? Sounds like you cracked a waterjacket.

prolly just a good reason to get a turbo swap and it is coming in a few weeks ill keep yall posted


btw does ant one wanna but some 85-86 headlight covers
i also have a bixenon headlamp setup w/ fog and wiring harness setup for 150 shipped offered to some but no return call....

no ballasts or bulbs

 

can you post some pics of the headlight covers or pm them to me?? are they clear or smoked? probably would have taken those bixenons off ya if they would have come ready to put on an 85-86. oh well, still waiting for my hookup

 

theyre clear and in a garage 30 miles away but i can get them this wekend also you gan just buy a grill from an 87-88 and itl be good enough

 

have you ever thought of taking an old set of covers and making a mold out of them to make your own set of clear lenses?

would eliminate your flat and i know theres gotta be werid gaps and wind noise with those things

 

that is pretty cool.

 

thought about it but i need some kinda plastic that i can melt and reuse any suggestions

 

they make a cast resin thats clear but its kinda brittle

theres also the same type of thing but in an acryulic but its kionda the same, i'll try to elaborate more tommorow ehn i am not so things...yea tonnorow
