Turbo Removal? C70 1998

First, the only reason to remove the turbo is to get room. You should already have enough room to move the exhaust header towards the firewall. Use PBBlaster.

Second, you should not have removed the cam sprockets. If you were careful, you can put the bolts back on in the same position. The holes are oblong because of timing considerations, this allows the timing to be changed and the only way it can be modified.

Use a zip tie to mark the exhaust cam, you do not want to get confused later.

If you have a hydraulic tensioner, compress it a little and shove a nail into the small hole to lock it into place. If you have the new style manual tensioner, order a new one.

The cam cover gets 'glued' to the head. Clean both surfaces with alcohol before mating. Use a very small foam roller to put the glue on evenly. It is thin and will not clog up any passages unless you pour it on.
The cam cover is what Tman is refering to, you can not bolt it down with the bolts. It must be compressed with a special tool - the valve springs will put a lot of tension on the cover.

Use new head bolts. Make sure the gasket is OEM and not Chinese.

Take a picture of the underside of the head so we can see the valves. And another one of the block with the old gasket in place, so we can see what you are up against.
