Hi all, as some of you will know I thought I had a 91 degree out timing issue...... well I think I found the problem after a very loud noise....

sounded like a box of bolts rattlihg round under the engine..... thought I had done the bottom end then It just dissapeared..

today I jacked her up and found the altenator bolt hanging out and the harmonic balancer spit in 2 pieces....

The inner part is tight on the crank, but the outer turns freely with the altenator belt on and independently of the middle section....

is this what happens when the harmonic balancer dies?

 

Any advice?

replace the balancer or fit an after market pulley.

Don't know how to solve your issue but it does remind me how much I miss my Zed and something going wrong on a daily basis.

Right...... need to move the z by saturday........ anyone got one locally that I can buy?????

Right......... today I found a spare bottom pulley / harmonic balancer and fitted her......

I noticed that there was a knock on the crank when moved by hand and started getting nervous...... Big End????

Nope......... It was the 4 bolts holding the flywheel to the torque converter....... removed the starter and metal brace pieces and re torqued them.......

Now the clatter I thought was the crank pulley is gone........YAYYYYY!!!!!

 

All I have to do now is sort out the stalling issue....... not fun with an auto box......... every time i let off the gas at junctions after giving it gas the revs drop to zero.......

I am guessing boost leak???

Plus I can't seem to get past 7 psi..... lack of boost as well....... even with profec b II at 100% I seem to have sod all boost.........
