Ok Bill the headcylinder is off and almost in parts... i unensambled the shaft just how haynes explains, and i am about doing little by little all the cleaning in the blok and headcylinder surfaces...

one thing still left is i havent found the correct spring compressor for this kind of head cylinder... it needs to be a big one going all over around the part from the up spring to the valve down and push one against the other... since the springs are hidden i cant use none other.

also i have seen on the haynes manual for ensamble the shaft back in the headcylinder i need some special grease? like ensambling grease? would you recomend some more expecific substance? can i use comon grease like the one used for bikes in the workshop? or should this be an expecific substance?

hopefully the gaskets will be here by friday, and i can finish next week.

thanks alot bill, have a great day!

This is the valve spring compressor in my Haynes manual. The manual is very old but the cylinder head in the picture is a B21A. You may be able to find one or even have one made like I did.

i need some special grease

If the grease is for the camshaft seal it is a mineral grease.

but that picture is weird thou, cuz you cant see anyway there to take the collets away, supposed to be a whole in or they would just jump out as soon as you let them enough space? haynes sayd to get them with a magne but still even when i tried with some kinda compressor i did my self, they seams to be really attached to the valve stem and wont come...

i will give it another try, in case i cant make it i will try renting some other compressor, some eassier way to do it...

mineral grease for the seal, would that be the seal in the front or the semi circular on the back? i guess the orange in the front... well in haynes they show the whole shaft covered in this,of course, white cuz its black and white, but could be light green substance when they are putting the shaft back, and i wonder if it is necesary?

thanks again, i will give it another try tonight since i think i was trying with the compressor in the wrong way. and some how this pic of yours helps me seen it in a diferent optic, since the one i got in my haynes its pretty more useless that this, and the compressor i got is more looking like this you sent too.

have a great happy day bill!

I have never seen a camshaft covered in grease to re-install it. I would think the grease would melt and eventually get into the oil with the potential to create problems.

The seal should have a light smear of grease on it to help it over the shaft. If any grease squeezes out wipe it off with a clean lint free cloth.

Hello there.
I am havving the most unexpected and, till now, unsolved problem.
I already received the whole gaskets kit, and looks very good.
So i decided to remove the manifolds to replace all the gaskets at once.

The prob came when the last bolt in the intake manifold, the one closer to the rear part wont let the manifold come out... the nut is off, but the bolt has ben rusted and wont let the piece go out... then what?

i have tried lots of things, except some blow torch... the part has been tried to prine lots of times so has suffered some little bending but still must get it out to put it back in perfect conditions!!!

kinda a desperate situation, I have everything to put the headcylinders back and just one bolt wont let me do it, incredible!

Do you have any advice?
I've tried regulas oir, fine oil, tabasco, wintergreen oil, will tried later brake fluid and if not the the torch but dont have a clue what to do with that flame there...

thanks for any ideas you come with!
have a nice day

If the bolt is bent it will stop the manifold because the clearance on the hole over the bolt is not very big.

Heat the bolt with the torch and try very gently to straighten the bolt. Don't use too much force as the bolt may snap. Heating the bolt may also make it easier to remove from the engine as it will need to be replaced when you put everything together.

thanx bill, but i didnt need the torch, the bolt was not bended... and well what i did was gentelly carved the gasket off the gap in between the manifold and the head cylinder, in the last corner till y saw the bolt in the gap, then started pouring break fluid and trying prining in the other extreme since there was some pivoting in the stucked blot, took less than 20 minutes then , little by little to get it out.
it was totally rusted, and even the pattern is not the same as the others... so i t was really badly rusted... eventhou some scratches in the surfaces they were not that bad and i made them even as soon as got them out.
right now i am doing the final lapping, so i might put the head cylinder together soon, if not tonight tomorrow night.

thanks for your advices one more time.

well i got al the gaskets and the seals, but then the stem seals are really tight to the guides... and some how they are hard to put in... can i put grease on them to make them go eassier?

any suggestions?

I already broke one and other went reallt twisted so i had to buy 4 more and make sure next time i do it perfect... tried with a ratchet but some how it would go not right... when i got the valve in would always look totally twisted.. then the valve couldnt been take out without totally f..k the seal.
hopefully will get the new ones tomorrow noon.

thanx again...
have a good day.

The stem seals should not be so tight that you are having to use a lot of force to install them.

One thing comes to mind, and don't be offended here, are you putting the seals on the correct valves? They will be very tight if they are going onto the exhaust valves.

I would not use grease, but if you wish to lubricate them then a small amount of oil should be OK. I have not come across this problem before.
