Porsche 944 Timing Belt Failure BENT Valves

Porsche 944 Timing Belt Failure & subsequent results. Got a 944 Porsche 2.5lLiter 4 Cylinder. Unfortunately it has an interference head. Some mechanics tried to "fix" it not knowing what "interference" means. They replaced the timing belt and bent the valves even more. They gave up the 2nd time around. Good thing they never finished the job as it would not have worked anyway.

Cylinder Head 105 - Valve Job Basics
Valves not sealing? Valves not bent? This is how you fix that problem. In this video I outline the basic valve job procedure. Cleaning the valves, cleaning the seats, cleaning the combustion chamber and lapping the valves in to make a better seal. Here I cover the process start-to-finish. It's the same exact process for pretty much all non-rotary combustion engines. It takes patience and perseverance to do this job, but anyone can do it. Reference your service manual for measurements and service limits. Everything else that's not in your service manual is in this video. I apologize for not having broken busted crap to work with in this video. It's more beneficial to all of you when bad fortune falls on me because it gets well documented, and many people watching these videos are looking for answers. If you have bent valves, you will discover it quickly once you chuck one up in the drill. You'll see the face of the valve wobble around while it spins. You'll see evidence of this damage on the valve seat. If it's bad, you may see damage on the valve guides in the form of cracks or missing pieces where the valve guides protrude through the head ports. Give all that stuff a good visual inspection. ...and if you doubt yourself, never hesitate to get a second opinion or consult a machine shop. They will have access to expensive tools that you wont find in your average gearhead's garage.

Changing your timing belt early can save you thousands!
Waiting until a timing belt breaks can mean the difference between a few hundred dollars to replace the belt, and a few thousand to repair your engine. David Rogers, the Monday Morning Mechanic, shows what can happen when you don't replace your timing belt, and shows you how you can save yourself some money by performing other maintenance at the same time!

1994 Honda Accord w/ Bent Valve
A video illustrating how your 94 Accord's engine will probably sound if it has a bent valve. Bent valves often happen in cars containing intereference engines, such as this particular model of Honda. They occur most often when the timing belt breaks during operation of the engine. This is an expensive repair, requiring the engine head to be dismanted. To avert this disaster, change your timing belt every 90k miles or sooner. This particular car had about 178k miles on it at the time of the video. There was a bent valve in cylinder 2, and the cylinder lost all compression.

Bent valves
This is what it means when a timing belt breaks.The valves bend after they hit the pistons.This is a test i use to determine quickly if severe damage has occured.A shop may use vacuum or simply rebuild the head as bent valves become obvious when refaceing them.Valves of a small stem diameter may not leak as the valve spring pressure pulls the valve straight enough to seal. But after repeated cycles of opening the head of the valve will break of destroying the engine. Also the valve guides are usually cracked in KIA HYUNDAI heads and the smalls pieces will go in the engine.I have seen guides cracked in all the 16 valve heads
