So u can measure when valve is at exact top

 

[bencorkill]

And can be used to test if a disc is warped i think

 

[discomark10]

oh! my old man has one of them! lol

 

[fett]

I got one, dont wanna do it all though, looks too complicated to interest me enough for a hobby lol

It looks pretty simple tbh, mount it so wont move ontop of the valve and turn it until its at top of its swing and lock?

 

[fett]

yeah but then can be tricky to set up and you still need the degrees sorting, I saw him do it on a 4x4 is born and didnt fancy it. I am doing my engine for enjoyment so I wont go where I dont want to. I went with the top of the line jp billet duplex timing set but chose the non adjustable one and a cam with 0.27 lift so I dont have to change the springs either

FINALLY ITS ON THE ENGINE STAND!!!! You cant understand how happy i was when i got it on!



Took the heads off



No sign of any liner slip on it, they all sit flush with the block. Ran my hand over all of them felt flat as a pan!


Span over the engine, cracked off all the bolts, damnn there on tight took a 2ft breaker bar with a trampoline pole about 1.5 meters long!



Hoping to get cylinders out tomorrow and crank if i have time or that can wait until sunday

Cheers, yeah the bonnet, basically i broke a discovery had a guy who wanted the bonnet as he had done that to his, but i was planning on keeping the bonnet as a sledge for winter, so said id wanna take his so swoped them over and as i had that laying about, took mine off and put in a safe place and just placed the batterd one ontop to keep water out engine bay

just one question, why did you take the engine to bits so much before you took it out?

Good question, i had time before engine hoist was sorted so thought i would get cracking on whatever i could whilst it was in there

 

[fett]

ahh I see

 

[bencorkill]

Done lots today!





Front cover off after wrestling with some rounded bolts, whiped out the irwin sockets and impact gun and they all came out eventually!
Play in timing chain, not as bad as i was expecting to be honest but still no good!

Then i started removing pistons, not much to say on that appart from my ingenious idea how to store them


Looks to me as if the rings are worn as carbon has built up to oil ring on a few.....

 

[bencorkill]

All the bores look pretty good


Set engine to TDC and marked with tipex on dizzy so i can set timing easily



Heres some of the crank, not sure how its supposed to look, but looks okay to me cant feel any lips on them.

Took cam shaft out aswell, no pics sorry will get some tomorrow, few of the lobes are almost squared with right angles on them, exaggerating but there are some sharpish angles on a few of the lobes! just got the block and bearings and the flywheel end to get off before crank comes out, any advice?

 

[discomark10]

all looks rather good to be honest! how many miles was it on?
What do you want help with exactly?
