Re: Timing belt broke, valves bent

When I took my head to the machine shop, the shop went ahead and purchased a head gasket kit from Fel-Pro. The shop needed the valve guides, they delivered the gasket kit along with the finished head. I used the gaskets, including cam seals, in the kit when putting everything back together. I suggest taking the valve cover (for cleaning) to the machine shop along with the head, if you go that route. I'd consider getting a replacement engine, replace timing components, maybe the PCV parts too.

I just pulled a tranny off a 96 850T with a blown gasket. If you need valves or an entire head let me know.

I just checked out my timing belt, and it looks okay. All I did was pull off the outside cover and look on the outer part of the belt toward the front of the engine. No cracks as far as I can see, but there is some grease built up in the bottom of the cover. I can't tell if it's antifreeze or not.

The green slippery sludge is likely pooled antifreeze and it's slippery stuff. It could coat the belt and cause it to slip.

Looks like you better add an Aisin WPV-800 to you order list.

Just as I thought I was getting off easy with a good belt, haha.

Such a critical part. In my dreams the company that manufactured the failed part would pay to have the vehicle repaired (when it fails within the operational limits).

No matter what, the company will find a way around it. They can give a lifetime warranty, and they'll get around it. There is a whole thing right now with 2011-2012 Hyundai Sonatas that have engines that fail catastrophically. As in, the connecting rods blow through the oil pan. Others just seize because people who buy new cars "because they can" don't understand the concept of oil, and that it needs to be checked regularly. Then, they come up with some ridiculous story that comes down to "it wasn't my fault."
Sorry, I'm too off topic now...

Finally got the head off yesterday. #5 cylinder has two bent intake valves and there are light marks on the piston of the #4 exhaust. Gonna remove all eight valves and check em. Best case, replace two intakes and run another hundred thousand miles. Any chance the #5 intake guides survived?

How many times do I need to repeat to never use non OEM parts for anything. Poor man always pays twice and sometimes loses everything. Many aftermarket parts are scams to steal your money. The parts, the material they are made of may not even be tested. They are not made to any standard. They have unpredictable life span. They are made to look the same and not to fail right away. One day it may be illegal to fix your own car because people install these questionable parts and make their cars dangerous to other drivers sharing the same road. Fortunately very few people work on their cars. If you are fixing your own car. Do your research to learn who the OEM supplier is and buy that if you want to save money and not want to buy Volvo OE blue box that costs more. For those who go cheap, the failure serves them right. Another problem is that those poorly repaired cars are often sold to an unsuspecting buyer. Continental OEM timing belt is only about $29 or less. The OP saved maybe $10 buying something else. That decision cost him his car. Proper research before the repair and purchasing OEM parts for the best price takes 10 times more time and effort than the actual repair. Those who don't do that research often regret it later.
