This is a how-to i wrote up 2day wen i was bored. hopefully it will come in handy for a few ppl. hmmm, wat would u guys n girls think of putting up a sticky HOW TO thread with different how to's in it. such as how to remove camshaft, how to install H/U, how to install digital dash etc...

Nice Brendan, this site needs more Technical threads like this. after reading it i was left wondering?
what is the torque specification for the camshaft bearing/rocker bolts and the spec for the timing chain sprocket and waterpump pulley on the camshaft?
The rubber "half moon" in the front of the head is available as a replacement part, new ones shouldn't need sealant.

I wish someone would put up a complete list of torque specs for the astron II and the V6 :pray:

P.S when ur working on cars/engines it's a good idea to wear shoes lol

Your a champ, a good guide. I like how things are explained, unlike my workshop manual, although good, sometimes it just doesnt give enough detail for a first timer like myself.

shoes... yeah my bad. yeah, the half moon probably shouldn't be put back on anyway. if it looks slightly worn, get a replacement. they are cheap as anyway and u can get them from supercheap.

you guys want torque specifications? i'll put them up as soon as i can. let me know wat is wrong with the camshaft writeup and ill fix it asap. i want it to b perfect for those first timers :D . point out EVERYTHING u can think of. it is abit vague in someparts, like the airbox assembly removal etc but i will need someone else to write that part for me cause my car dosen't have the stock airbox assembly haha.

why a write up, its gotta be the easiest thing. should we put a write up on how to start the car aswell?

Yeah!! That would be awesome, maybe if all the 1st Gen owners who have done modifications should write a simple tutorial?

oy im gunna make a petitiiopj to get a hot0to threead going and ce swat happens.but ill do it wen im ssober.

You're going to wear a petticoat where?
