tools needed to replace head gaskets - ZR-1 Net Registry Forums

I need to find out what tools I need to buy to replace the head gaskets in my 90, and where I can get them ? can anyone give me a list. I already have the gaskets needed just need the tools to do the job

You have to pull engine. And you need a good torque wrench for Head Bolts and a set of metric flex head ratchet wrenches and set of 3/8 metric sockets. And a set of Torx T handles.

What Cliff said its a pull the engine time. You will also need an engine puller etc and it's a bear of a job

I'd mostly be concerned on how to re-time the cams. The rest of it looks like pretty standard tools required for r&r portion. Ben has some clever substitutes and tricks in his LT5 repair thread which would be a good read I would think.

the cam timing tool are what I really need to find out about .pulling the motor isn't a concern.

All you need is a 15/64 drill bit to pin the camshafts

You also need timing chain mechanical tensioners.

Or you can visually even get closer if you want to advance the pinning hole in the camshaft a bit past or before the pinning hole in the Camshaft Retainer.

Camshaft Timing
Camshaft Timing (Locking the Camshafts) and Camshaft Lubrication

I have removed the Heads with engine in car but then camshaft timing as well as Head Bolt Torque application is almost impossible with engine in car.

Pull the C-Frame, the Transmission, Bell Housing, exhaust manifolds....pull Plenum and IH to make it easy. I have actually installed the LT5 with Headers attached

Oh.....I pulled windshield wiper motor and cover off AC Evaporator just to get those out of the way for easy engine installation.

Yep....and lifted LT5 engines as well as ZF S6 40 transmissions several times with no issues with knuckles

I made my own timing chain tensioner a for camshaft timing and used the drill bits above. I also used the ARP bolts Marc Hiebeck sells for the camshaft timing gears.

You do not need the lt5 tools to do this job.

You can do it with the engine in the car but it's just easier to yank it out.
