HELP! Blown engine???

[blackGSX2g]

Well, I just had a brand new evo 16g turbo installed about 600 miles ago, and this morning I was crusing on the interstate and I noticed it started chugging a bit. When I got off, the thing stalled and when I restarted it, it sounded like a metallic chunking sound. I pulled over and shut it off and the coolant hose was about to pop and coolent temps were 246* on the logger. Every time I restart it, it makes that godawful sound and stalls out. What could possibly be wrong? Its sitting in a gas station right now cooling down so I'll look at it later. Any suggestions?? Please help me!

Oh yea, BTW I checked all the belts and they are good, no oil leaking...just a tiny bit of coolant from the hose from being so expanded. No oil leaks, no clouds of smoke, pulled the dipstick to see if there was metal chunks on it...nothing yet, but it was too hot to drain anything out to check. I'm gonna go in an hour or so and pull the plugs and see if the pistons are still there..grr. I'll update when I know more.

pull the belt off the water pump and see if theres any play in the shaft or if theres any noises there could be your pump took a dump on ya

How many miles are on it? Good compression? No bent valves or warping?

Thanks

UPDATE:

Well, I heard back from my mechanic and the bottom end is pretty much ruled out. Timing is fine, so it didn't jump a tooth. According to his best guess at this time, its something with a lifter siezing up or something, because the sound kind of comes in waves, whereas a bad rod bearing would just be constant. Does this sound right?

Hm. I don't like the lifter idea- so far, it's been unheard-of with my history in DSMs.

Since you've had the car, how high have you run the RPMs, and how often?

 

[crashed97tsi]

GREAT timing advance.

how "great". You do know too much timing is a bad thing right. Just being captain obvious here so don't take offense and start a shit fest

 

[blackGSX2g]

Since I've had the car, I've rarely gone over about 6500 rpms. The stock t-25 didn't push much after 6k, so I figured why bother. Since I've had the e16g put on, I've taken it to 7k once to log my timing curve. Other than that, I usually stay out of high rpms.

As for timing, its a nice curve that starts off at about 11* WOT in 3rd, and has an upward curve to about 18-20* with no dips. I started the 3rd gear pull at about 2800 rpms.

Defiant:
Do you have any ideas on what it might be in the head? Should I have him take it apart and look at it for 350?

 

[1fast97gsx]

I'm still leaning towards the rod bearing idea. However I suggest you do the headwork yourself as it is fairly simple. Doing the timing is the only remotely difficult thing and I wouldn't worry about that too much either as long as you take your time with it. As mentioned, a seized lifter isn't a common dsm problem.

 

[1fast97gsx]

hows your compression?

I just don't know. From your original post, I'd have doubled-down on it being the timing belt. But your compression numbers seem to rule that out- bent valves don't build any pressure. I strongly disagree with the idea of a seized lifter, that just doesn't happen on halfway-maintained DSMs, so I'm not initially impressed with the mechanic you're dealing with there.

I wonder if you spun a balance shaft bearing?

 

[blackGSX2g]

I haven't tested compression yet. Its been sitting at the shop and I've been nervous to crank it over to test it now.

 

[blackGSX2g]

Would a bad balance shaft bearing make a noise that sounds like its coming from the head? I couldn't hear anything from the belt area, but it is kind of difficult to differentiate. Also, it seems to be burning a bit of oil if that helps any. I know its not the turbo cause it was just replaced.

Oh, crap then. I got that crossed from someone else's grenade. Then I'm back to jumped timing and bent valves. Probably intakes, maybe intake and exhaust. Grab a used head, give it whatever reconditioning you can afford, and throw it on. Or, have it done.

UPDATE:

Alright, when the timing belt was removed, my mechanic found the problem to be the balance shaft. He said it didn't rotate freely anymore and that I would need a new engine. I was under the impression that DSMs dont need balance shafts to run, but I have no experience with this sort of thing. Does this sound right? I can't afford a new engine :thumbdown

I'm in Mundelein, pretty darn close to you.

haha so was the other guy... weird... but hey, lets not turn this into... in defiants words... a thread between 2 people who could throw rocks at each other... so PM me if ya wanna talk

 

[crashed97tsi]

due a searchabout balance hsaft belts bearings freezing. I THINK most people got a BS eliminator kit and ran fine, but it has been a while since I checked. I believe the digest is another good source. Sorry man, but I can't offer anymore help than that. Was the rest of the belt lined up? Was the BS belt frayed or torn or anything.

Ah. Post #41. Trouble is that when the bearing fails, the oiling system feeds the bits of bearing around the engine, ruining the other bearings. IF you got really lucky, the filter would have caught the chunks and saved everything other than the balance shaft bushings and the oil pump. But you have to do a tear-down to find out what's ruined, where and how much. If you're paying a mechanic an hourly rate to do it, the cost soon outruns the price of a replacement engine.
