Heys guys,

I have an Evo 3 which i bought because it needed a "slight" head job. The timing belt popped and the valves were bent as suspected when my mechanic took the head off. I got another head in fairly good condition and took it to the machine shop to get checked out. My mechanic installed the new head and the car started up. It hesitated but it started. I then drove the car about 40 or so feet when the engine just shut down and when i go outside the car coolant was all underneath the car.The car wouldn't start any more,the cam gears weren't moving AT ALL either when i tried to crank it over.I called my mechanic ASAP and told him he came there and said it looks like the timing belt isn't any more good which meant I BENT the valves within 10 seconds of driving and you also have a faulty water pump and your oil pump too. HE basically told me that because the oil pump wasnt working, that it starved the head of oil causing the valves to bend again.

Ques 1. Does this make any sense or is this story bogus?

Ques 2. Can a faulty oil pump actually cause the valves to bend?

Ques 3. What could posibbly be the problem the car started but just shut off randomly.?

 

Any body?

 

after 10 seconds of running, no the valves would not seize

a bad oil pump would spin a rod bearing and ruin main bearings in the bottom end before " bending valves"

and the act of bending valves means your pistons made contact with the valves them selves.

basically it sounds like your timing belt slipped or came off

and ya if the coolant is pouring everywhere maybe your water pump has blown so simply replace it

id use another mechanic honestly seems like hes guessing

 

I'm into lists today so here's a list of the three situations in life when it comes to cars .....

1. You know nothing about car mechanics. In this case you have to take the mechanic's word and pay.

2. You know as much or more about your car as the mechanic does. This isn't that hard, just get a copy of the service manual and read. Then you can tell your mechanic what you want done. If he follows your instructions and it still isn't fixed you have no one to blame but yourself. The trouble is, the mechanic will always think he knows more than you do. For example, I told my mechanic my car needed new side bearings in the differential. When I picked my car up it had new pub bearings and axles. Driving home it still made the same noise.

3. This brings us to where, being disgusted with trying to get any mechanic to do what you want, you get out the tools and do it yourself.

 

Story is bogus. If he installed the head and the timing belt, it sounds like he installed it wrong and the timing belt skipped and bent the valves.

A faulty oil pump cannot and willnot bend the valves.

The problem is he installed the timing belt wrong. Did he reuse the old belt by any chance?

This is all his responsibility. Dont let him fool you into thinking anything else.

 

Thanks for the reply guys.
So worst case scenario is that the valves are bent again? Or can it be that coolant got into the cylinders and this is also stopping the engine from turning over. Like i said when i crank the car the cam gears nor any belts move, AT ALL. Just being sure that my block is not seized up.

 

Yes, he used the belt from the engine i got the head from(which was like new,the belt that is) and he also told me I didn't need a head gasket and reused the old one.

Like i said the car started fine, Drove the car about 40 or so feet down the road and the engine just shut off and coolant was all over the ground. check the dip stick and oil was still in the motor. Just trying to see if my entire motor is seized or its just a head problem I have to worry about?

 

He is an idiot if he tells you that you didn't need a head gasket. You always replace the hg when you take the head off. The reason the coolant was all over the place was because the coolant passages prob didn't seal and just pisses everywhere. Another thing from your first post is it sounds like he didn't do the timing belt correctly. When you redo any type of t belt stuff on older cars like that always replace your tensioners. This will assure nothing will go wrong. Another thing is did he check for square ness of the new head? How did he know it wasn't warped if he didn't? Another thing is too why didn't he replace the timing belt when he put the new head on? It sounds like this guy has never worked on a interference motor before. Just my .02

 

Have you tried to find out where the coolant is leaking from?

 

More then likely its the hg not sealing at all being his mechanic reused it.

 

My "piece of ****" mechanic told me it was coming from the water pump. I will take the head of next week and see what I find. Whats concerning me is that when i try to crank the engine over none of the cam gears or belts in the ENGINE MOVE at all. Can this be because the engine has seized completely or its just something in the head?

 

More then likely the t belt slipped and the valves are stuck on the piston. I would take the t belt off, get all new timing stuff to start, get the motor top dead center where all your timing marks line up, put the belt back on and give it proper tension and go from there. Then once all that is done turn the motor 6 times by hand and make sure everything still lines up. The evo3 is the same as a 2g eclipse/talon so there are plenty of write ups around to look at. If everything spins freely with no problems then you should be ok. But if you start turning it by hand and the motor wont turn over then yeah valves are in the way. Once you get the thing running again do a compression test and that will let you know if the valves got wacked or not.

 

Given your mechanic's performance thus far, I'd imagine that you're leaking at the head gasket as cursedsm said but you will still be better off knowing for sure. Pop the head off and if your cylinders have coolant in them then you know what you're dealing with.

 

If you can see if you can find someone local that has worked on dsm's. The motors are the same and they should be able to help you.

 

So this guy used your old timing belt and head gasket? Am I reading that right?
