Default something MAJORLY wrong

ok.. i need some serious advice here. I have a 98 RS with a minnam stage2 turbo kit on the car and a Tec-II. I took the car to have new head gaskets put on. While the heads were off they checked them and said that everything was perfect as far as the heads went. The guy replaced all seals in the engine except rearmain seal. put the engine back together today.. went to start the car and once it tried to start on its own it had a HORRIBLE clanking sound and the engine shuddered violently and then died. I have no clue what is wrong with it. he told me he has never had a car do that to him before. He used to be a subaru tech and knows about WRX's and stuff. but he told me he has no clue as to what the car will do with the Tec-II. So, i need to know if anyone here knows what is the matter and what i need to do to fix it. I need this car running ASAP. thanks for reading.

Did you check all your sensors for the TEC2? Crank angle, etc?

Hopefully the guy didn't do anything stupid and now you have bent valves....

well it is showing a CEL.. we checked it and it said low voltage on all injectors. but he told me that was probably because of the Tec-II

that clanking sound makes it sound like its a mechanical problem... if you had the TECII before the gasket replacement I don't see why it would be the TEC...

I would say mis-installed timing belt tensioner.

I agree f you put the timing belt on wrong, and crank over the motor... bad news.. he should have hand cranked the motor wit the timing belt and cam sprockets visible to make sure tha everything was moving the way it should.. ie, the TDC marks on the cam sprockets should have come back to TDC once the engine was cranked.. you know?

Definately sounds like he either timed the thing wrong, or effed up the tensioner assembly. The bit about the Tec-II being at fault is a load of garbage, sounds like he just bought you a new top end Start looking at stiff valve springs and some nice 5 way valves. Enjoy your new 7500 RPM redline.

The heads are probably fine, he would have had to REALLY screw up hardcore to have to buy new heads. If it's what it sounds like he's going to owe you some new valvetrain parts. Probably just springs/retainers/valves, but if things are really bad, a new cam as well. If this is the case just drop the TINY amount of extra money into stiffer springs and better valves and set your rev limiter to 7500 or so. You'll get a pretty obnoxious power increase and a much more fun car to drive for very little money on your part, just some downtime. I'm sure you can make a good case for him buying you the upgraded bits since you have to deal with all the downtime.

You can try to turn the crank over with a wrench and see if it makes noise. I would make him take it back aprt though- actually I don't know if I'd trust him to work on it at all anymore. It's really easy to screw up timing on the 4 cam if you don't have the cam locking tool.

Default Questionable

I've done DOHC timing belt about 30 times, don't ask, and while it is possible to screw it up you have to be pretty in competent to do so. I would deffinately question this guys work. But it does sounds like it's mechanical not TEC related and like the others said probably a misaligned belt. Do you know if he replaced TB tensioner when he was in there?

who is this guy? is it your friend who did the work? Most decent mechanics will warranty their work for a certain period of time. I would make him fix it, and if he can't make him pay to take it to a different mechanic that knows what they are doing.

ok guys... found out what was wrong.. he tore the whole engine apart today. the new head gaskets were thinner than my old ones and the pistons were barely hitting the valves. he had to heads rechecked today and they said the valves were fine and did a compression check. all checked out ok. so he is going to have the pistons shaved a few thousands of an inch so the valves will clear and put it back together. So, i will have my car saturday! *claps*

There should be no reason to use a new headgasket other than stock. This sounds fishy to me.

this sounds seriously fishy..... what did you have done to the motor? If you have new pistons and rods, perhaps that might cause the piston valve tapping. if the rod is too long... this could cause a clearence problem... This doesn't seem right to me at all if, all that he did was put new seals in.. seems like he did something seriously wrong.

we found out that the heads have been shaved before which is why the head gaskets were not thick enough and caused the piston tapping on the valves. but he is going to shave the pistons anyway since they are already at the shop for free. So, either way the car is getting fixed. im happy.

Default DOHC gaskets?

Are you sure he used the DOHC gaskets? They are thicker than the SOHC gaskets. The SOHC gasket would easily explain the problem. When my heads were O-ringed they were shaved, I asked them about it effecting the tolerances of the valve clearance and the compression of the motor. The told me that the amount they took off is so microscopic that they would have to do it something like 40 times for it to effect anything.

The head milling is a complete BS excuse. The wrong gasket had to have been used. Typically when a head requires a slight deck job 10 thousandths is typically taken off, that is so miniscule that it is impossible to cause any valve clearance issues. If anything more than 30-40 thousandths has to be taken off an alluminum head, the crystaline structure of the metal is so screwed up due to warpage that the head will NEVER hold a proper shape and should always be scrapped. Even assuming a head that had 40 thousandths taken off of it was used, I HIGHLY doubt that would be enough to cause issues with your valves tapping. I would be more suspect of the guy setting the valve lash improperly combined with an improper head gasket.
