hey newbie here lol

You should be able to spin what remains of the bolt out pretty easily. I have used a fishing magnet before for doing it, believe it or not. If worst comes to worst, just get a drill on it and spin it out. Then get new hardware and a torque wrench. It should cause any lasting damage.

always use new hardware for this very reason

Yay! for locals :) ... took it to a machine shop for a mere sum of 350 bucks it was pressure clean, valve seal replacement, angle job, and pressure tested and all in all slap back together. It was near arundel mills, it sure beats the hell out of doing it yourself.

Hey, I'm pretty sure I took it to that same guy back in the day. He was on Rt. 1 quite a bit north of Carmax on the right. He was this old man doing it by himself in this commercial building, and he knocked it out. It was some random Hartge head that was on this car I bought.

There was another guy near arundel mills though.

That guy seems to have a good rep, but he took on rebuilding my 2.7 bottom end and ended up f*cking me out of 2g's and still has the whole motor. Jackson the guy seemed pretty nice, but his wife was a real piece of work.

HOLY CRAP, okay so i put on the new camseal and o-ring and slid the guide cover back onto the cam. when i was tightening the bolts for the guide cover they felt like they werent getting tight. so i was tightening one and the bolt head broke off!! i just got f'd in the ass soo bad now, i dont know what to do! any suggestions? heres a pic.

[gtdragon980]

okay so im back on track and i have the new rockers in, i need some help now with the eccentrics. like what should the clearance be btwn the rocker and camshaft?

[gtdragon980]

oh no i fixed that, i thought it was off too but once i fixed the bottom, they both lined up perfectly..and yes i did slide the arms off the valves, but im still having trouble. i can post some pics of how much its moved if thatll help!

[thereisnoyun]

after a second look at your pic, the top TDC seem to be off to the left. You sure there isn't any internal damage? I did one timing belt and rebuilt one m20 before... and it was never that off to the left for me, it was always straight in teh center on the line for the top TDC.

Petroleum based lubes are fine. Try not to pry too much!


Did you slide the rockers off of the valves yet?

[gtdragon980]

is there like any tools you recommend to use to get enough leverage between the firewall and engine head? and it is safe to use lube in there right?

[StereoInstaller1]

The easy way to deal with the rocker arm shaft removal is to slide each rocker arm off of the valve stem o the arms have no tension, then spray-lube the shit out of the whole damn thing so the shaft will slide out.

That timing mark on the outer cover? When re-assembling, don't worry about it. There is a much better mark on the crankshaft itself, and a nice little "V" cast into the belt guide. Use that and the cam alignment mark you already posted.

Line the cam up, line the crank up, install belt and rotate by wrench 720 degrees just to make sure.

Yay! for locals :) I'm in MD too in College park.

btw, when we rebuilt my gf i engine top end, we just unbolt the whole thing and took it to a machine shop for a mere sum of 350 bucks it was pressure clean, valve seal replacement, angle job, and pressure tested and all in all slap back together. It was near arundel mills, it sure beats the hell out of doing it yourself. Dont forget to replace all the seals so there is no oil leak.

I might be around gaithersburg on Sunday, if you need a hand.

[gtdragon980]

bump

[gtdragon980]

yeah around 76,xxx. newb question again, is there any good ways to get enough leverage to slide those shafts out w/o damaging anything??

[kenika65]

wow looks super clean, must be low miles? be sure to replace the front cam seal and don't put a water pump with a chepo plastic impeller on it.

[E30_fiend]

Well luckily it looks like you broke only the #6 cyl rockers. Those are the easiest to replace because they are the first to come off the rocker shaft as you're pulling it out. Just unbolt the rocker shaft and it will become movable
. The rockers move side to side on the shaft so they will slide off once the shaft is far enough out of the head.

Its actually not that hard. Give it a shot and just feel lucky that you didn't break a #1 or #2 cyl rocker. You'd be hating life for sure.
