broke timing belt on 99 Forester HELP !!

[Hondasucks]

Not likely, unless he was running at 6000 rpm's when the belt broke!!

 

I agree with Ken, about the only way you are going to bend valves on an EJ25 is if you break a belt at high RPM and the valves happen to stick wide open. The four cam engines are a different story, as the valves can and will contact each other if the belt breaks. The last four cam I saw with bent valves was one that had an aftermarket water pump come apart.

DFound two nice used heads with 60k miles for $174 including freight. Just in case.

let us know how this turns out. Did you double check the T belt install marks yet.

That is a good price for used heads. Did they come fully loaded?

[jimrichard]

Going to double check belt and alignment his weekend and do compression test. If no good then heads are coming off.

[jimrichard]

Heads are complete except for sprocket.

[Hondasucks]

Pretty sure you are the one that needed/wanted to see this, but if not hopefully the right person sees it. The below picture is of a crank sprocket. The screwdriver on the right is pointing to the timing mark that needs to be lined up with the center line on the timing belt, the black pointy thing at the bottom of the picture is pointing to a triangular mark that is on the face of the pulley, which is easily mistaken for a timing mark, but as you can see it is NOT the mark you need to line up with the belt! (I'm not sure what it is for , and my master tech didn't know either, our theory is it's there to confuse non Subaru technicians )

The triangle is to indicate TDC for the #1 piston.

[jimrichard]

So line the mark up with the oil pump mark to set timing ? Or use the triangle aligned with the oil pump mark to find TDC on # 1 ?

[davebugs]

There is a mark by the crank sensor to align the mark at the REAR of the splined pully to.

[ron917]

Do not use the triangle for timing belt changes. Use the line on the reluctor* tooth . Using that line, all of the pistons are at the halfway point in their cylinders, none are at TDC.

 

*reluctor is those extra teeth that stick out on the back of the sprocket. The teeth are sensed by the crank position sensor (it's a Hall effect sensor) so the ECU knows where the crankshaft is.

Where did you find them? junkyard? I'm looking for a head for a 99 2.5

[davebugs]

I got heads. Not that cheap but known good. I'd need to tear an engine down to get them. Unless you want 97/98 DOHC heads w/bent valves due to an idler failure - I have them on the shelf. I think they are 97 (from memory) because they have the shims to adjsut the valves).

 

PM me if interested.

 

I have a set of 2.5 DOHC form an engine with bearing issues.

 

And a set of 2.5 SOHC heads(Forester) from an engine with bearing issues.

 

Both engines are complete at the present time.

 

Both have around 150k on them.

Pulled old heads and yes valves are bent. Pistons and bores look good. Transferred old sprockets to new heads and will put back together next week. What a job getting those heads off. WOW.
