      Anyone had a shop do this for them? Does the motor have to come out or can they pull the oil pan and drop the crank rods then pistons from the bottom? Any idea on the price?

      I have not done this on the 24v but I believe the top chain can come off of the cams without pulling the trans, so just the oil pan and head need to come off to pull the pistons.
      Can I ask why you are replacing the rings?

      Still low compression after a new head gasket and valve cover gasket. Its the only thing I can think of that's causing it besides maybe bad pistons. Its at the shop now and they are checking it out.

      Well to keep the thread updated the shop has said that they have filled the cylinders with nitrogen and the only leak they have found was on the intake valves and the worst compression was 75. They want to replace the head because they say the guides aren't serviceable? Is this true? I think they are pressed in but does that mean they can't come out?

      I just had all the valve stem seals and a few guides re-sleeved on my 24v head, so I'd say it's serviceable?

      I'm also having the piston rings done too.

      Guides are serviceable. Pistons come out from the top. Improper cam timing could be the cause of the low compression if one of the cams isn't correctly timed.

      The shop claims that VW doesn't sell replacements so he want to get a used head with 60k miles and rebuild it for and extra 500. Would timing cause the compression to be that low? Its lowest was cylinder 3 at 75 psi

      Valve guides from Tehntonics are $7 and $7.50 each and a guide will not cause low compression.

      That's what I thought. They think the head is bad now because of the compression its been to two machine shops already. Now he said guides are bad and non serviceable which is bull. I'll have to have a long talk with them on Monday morning. Not sure if they would use the TT parts they like to stay OEM so they offer a warranty on work.
