t belt broke
« on: July 24, 2010, 11:30:27 am »
Howdy Gang,
 The t belt broke on our '85 n/a Golf . The belt and all had less than 15,000km.
I don't know if it had anything to do with driving into deep mud puddles on our long driveway. The alternator belt would squeel when it got wet.
I pulled the head.

 I can't get 2 of the lifter out of the head.
There isn't any adjusting shims on the lifters so it must be a hydraulic lifters--does that sound correct?

I searched but didn't find what I was looking for.

I have a valve spring compressor(big C clamp looking tool ) is there an adapter to get into the cylinder head to remove the valves?

If I understand correctly the notches on the head gasket tell how much the pistons extend out of the block -- this H/G has two holes/notches

any good links for me to read .

thanks

hank

Just curious...what brand of TB and tensioner did you have?
There is a tools thread around here somewhere.

Not true. It greatly depends on the engine speed at which it broke and how long the vehicle was kept in gear after it broke.

85 should be solid lifters but if there are no adjusting shims on the top then it is a hydraulic engine. If you can get those 2 lifters out without destroying the head you should be able to salvage it. I would focus on them before looking at valves. There is some info in the FAQ on homemade tools for removing the valve train.

There is no guarantee the right HG was used by the previous builder.

Not necessarily. In my case, when the damaged t-belt slipped out of the cam pulley, I was expecting a FUBAR head, but luckily replacing all the valves, cam followers and camshaft (it broke), did the trick.  :)

In the OP case, I'll have the head tested, and the piston protusion measured.

Weld a bolt to the top of the stuck lifter then use vise grips to pull it out.
Worked for me,

I second the weld something to it or set it up to use a slide hammer to pull the lifter.  If you are going to have a machine shop look it over, which you should, leave it be and let them deal with it.  Otherwise get the lifter out, buy a new one and see if you can get it to move in and out freely, same with all the others.  After that we can move on to the next thing to check.
Many things we do naturally become difficult only when we try to make them intellectual subjects. It is possible to know so much about a subject that you become ignorant.

Sorry if this thread is a bit confusing now, I just deleted a bunch of posts that weren't contributing to the OPs questions.

Not sure of the brand but we bought the timing belt kit from eBay along with a set of timing tools.

 When the belt broke I was driving slowly in town
I pushed the clutch in and coasted to a stop and checked under the hood and saw the broken belt when I undid the top cover.

Thanks for the homemade tool link some good tools there.

I'll try welding and slidehammer trick


 What would be a reasonable price for a good rebuilt head?


So nobody else gets a warning when signing in?thanks
