Head removal

[Timd]

afternoon all

im planning on getting the head of my rb20det recond and will be removing/installing it myself. RB engines are new to me so i was wondering if ppl might have some tips or things to look out for when undergoing such a procedure.

Ive priced a VRS kit from nissan which was about 250. Components include

head gasket

rockers gaskets

manifold gaskets

cam seals

valve stem seals, i think that was all.

are there any other little gaskets i will need for the job that arent included in this kit?

Also, would i be stupid to re-use the old head studs? or wont it be a drama.

i dont have a manual so ill be taking it as it comes, so if youve got any tips for me, please fell free to share!

cheers, Tim

Do you need the tension settings for the head bolts ?

hi cameron

im right for the head stud torque settings. But thats all. id love any other head related torque specs if you know them?!

[cameron]

Yeh no worries i'll track them down for you.

I think it shouldn't be too difficult, as long as somebody else has assembled the head for you.

Not that I've done it myself.. but I have pulled the head (well actually the whole motor apart) *off* an RB (rb30) and that wasn't too difficult not ever doing it before.

Sure, getting it back doesn't mean its necessarily so easy but I'll tackle it sometime.

the exhaust manifolds are often cracked, u will probably find broken studs..

find out the correct torque settings for the exhaust manifold studs and make sure u dont over/under tighten them, and that they are all the same.

also in case ur not sure u gotta torque the head down in stages, and in sequence..

i think if u do a search specifics will come up, cameron looks like he can help with the specifics anyway!

get a copy of the workshop manual before you try this mate.

I have a copy and the amont of info it has is unbelievable...

its too big to post up here but do a search. i saw it in a post and downloaded it from the link given... about 30 meg or so i think.

cheers,

Waz.

ive done searches on manuals for rb20det more times than i care to remember. pretty much every other rb motor but the 20det

Cameron, that would be good, much appreciated

Just be careful not to pry the head unless you are 100% sure you have taken out ALL the bolts. (And drained the coolant )

The main bolts are obvious but there are a 3or 4 small bolts on the corners that are NOT!

There is also a lage bolt at the front in side ways near the Steering pump mount if I remember correct.

If all the bolts are out it will come off fairly easy so be careful and dont force it too much unless you are sure.

Damned if I know how I am going to remember to get it all back together again. :Oops:
