FFFFFFFFUUUUUUU Head warpage.

[TimKninja]

So I FINALLY get around to puttting the head on my engine block . I took the one off my parts car, as the one on my car was borked with a seized intake manifold stud. And this one looked better. Got it off, let it sit on a tire, resting on intake manifold and exhaust manifold put it on, torque to 22 then 90 degree two times. and I get this.



and then I was worried, so I went back to the garage and tightened it a bit more. and got a better result.




so my question is does this look satisfacotry to r3v? or Will I only find out when its put all abck together, I go to start it and it leaks errywhere.

I DONT plan on keeping this b27 long, maybe for another year or two. gonna swap in an M30 or M50....something better. But I need my car running again. SO I Really dont wanna take it machine shop. unless I have to.

another off topic question, the line that connects the master to the slave cylinder's hose. The inbetween hose, is just a peice of hard brake line, right? I allready bought the hose that goes to the slave, but I cant seem to find anything else. Am I rite ?

fix that intake stud WTF?

Wait, you swapped your head because of a seized nut?

Did you not resurface the head before installing it?

[lennon]

it sounds like he took it right off the parts car, set it on a tire or something, then put it on. if thats the case, thats your problem OP. you cant just pull a head off one motor and throw it on another without atleast having it checked/resurfaced. did you use a new gasket? also wondering why you replaced the head just because of intake stud?

[lolcantturn]

To make you feel better, when I put in my new headgasket I didn't get the head resurfaced. I bought pretty good quality headgasket kit and torqued it down properly. That was about a month and a half ago. 1600+ miles later, much revlimiter bouncing, triple digit speeds obtained and it's still marching strong as ever.

Undoubtedly, this is not the correct route to take at all, and if I had to do it again I'd get it resurfaced, actually I'd get a new head all together.

[TimKninja]

SO Im an idiot for not getting it resurfaced. wasn't sure if it was necessary. Now I see it is. tho now its flusher with the surface. Im gonna look up a reputable machine shop tomarrow.

New gasket, new bolts.


intake manifold stud was seized on my other head. so the intake manifold would NOT come off . This head has less miles on it, and sounded healthier when it ran, other one had what sounded like a stuck lifter.

Yea I read that Nil, made me think "Well his car runs fine!" and your head was borked too.

Still not good but it's a lot worse to do when the head is from another engine.

Well, now you need to pull the head off, resurface it, and buy new bolts and gasket.

These heads do not have lifters.

okay first you need to check that head with a straight edge. By straight edge I dont mean a ruler purchased at wal-mart. You need a legit straight machined within some ten thousands of an inch.snap on sells em. Rule of thumb for manufacture specification is .001 thousands warpage for every cylinder. So for you .006

Just because it looks flush with the service doesnt mean its not warped. You can have in machined but if the warpage is extensive you may need a new head.

Also dont expect that head gasket to last long if you try and drive it. Also you cant re use the gasket you just installed. but im sure you knew that.

[TimKninja]

Well, lesson learned , thats what i get for doing it half assed. i should also purchase the head gasket thats +.003 right?

Are the head bolt washers re-useable?.....fuck it ill buy new ones.

Still heard a worrying valvetrain noise coming from old head. trust me this head has much less miles and less oil burnt on.

will most machine shops take the head with the valves and everything still inside them?

knew i wouldnt be able to re-use old gasket and bolts, im not that dumb.

What do you guise reccommend for cleaning the blocks surface? i was using brake cleaner and a wire brush and got off alot of the gunk.

[riceh8r]

@ $125 will get you a shave, and labor on new guides and reseating. check your head thickness though... 4.909" is your minimum...:)

[TimKninja]

So I got the head rebuilt payed $415 :/. He said it was 4 thousands of an inch off, should I use the optional thicker gasket . He said the stock one would be fine .

what

[Kershaw]

4 thousands of an inch is within spec.

and $415 wtf. all for a seized bolt?

[TimKninja]

hmmm...thought it was a bit much. but its a piece of mind thing as I plan to make this my daily driver.

So stock gasket then? Goetze is a better brand then VR I assume.
