life sucks.....time to rebuild agin?
So I was driving down the freeway last sunday and my car started sounding funny, kinda like a diesel truck. I wasnt losing power or anything but I got off the next exit to check it out, once I started slowing down it just studdered out and died. I checked for cels and there wasnt any, so I popped the hood to take a look and everything looked ok. I then had my wife try to turn it over while I was under the hood, it made a very loud rattle like noise and I can see and hear something hitting the inside of the timing belt cover. I cant get in the shop till friday but Im assuming my timing belt broke? From what Ive read if your belt snaps while driving you can kiss your valves good by. Im just out of warranty on my new motor so no relief there witch sucks big time. I just put a ton of cash in on the last build so I hope this wont be to bad. What do you think, probabley have to build a new top end or is the whole long block toast? Any opinions on the worst and best case senarioes?

Ouch :poorme:

Yes, timing failures at freeway speedway are certain destruction of valves, which means a costly job. If you are a DIY'er you could save a ton. I'd recommend looking at possible parts warranty on timing components, since it's usually the tensioner or more commonly the cogged idler that fails. Some parts warranties cover labor, which could mean the job could cost you zero.

First thing though, is to determine exact failure and cause, making a carefully chosen decision on who you take it to (unless you DIY) The first way you can find out if the short block is OK is to look at your oil. The dipstick will tell a little, but draining will give you a lot more info, based on what (if any) metal flakes you see present.

Typically a timing failure won't take out the short block.

Unfortunately, your description doesn't sound like a timing failure, as you would have lost power immediately. It sounds more like a catastrophic bottom end failure.

Hope it's not too bad for you.

Worst case: You need to buy a new complete engine.
Best case: The woodruff key broke off and your crank pulley is hitting the timing cover.

I'm praying for you brother...but sounds like a diesel truck probably means the bottom end fell out on you. Especially if the noise was consistant with the revs....IE rod knock. Unless you get lucky...It'd say to strap in and hold on.

I'm not wishing this on anyone, but I built my old Prelude motor and 8000 miles later the crankshaft broke in half, which made it sound like a diesel, and the pulley wobbled back and forth out the side of the block. It sounds oddly familiar to me. When I built that motor I had the stock one re-machined, and the journals for the rod bearings were weakened too much and that's where that failure happened. Even though most of the other parts were like new I trashed that motor and just started with another one entirely. I hope that's not the case. I don't know what I'd do if my most recent build on this car didn't hold up. I just hope the best for you, man.

well its in the shop just waiting on the call. I took the right side of the timing cover to see if i could see anything, the belt looked good but was very loose. I couldnt see much else, but before I put the cover back on I noticed some metal shavings stuck to some grease. With the belt that loose I know somethings up, guess well see. It diddnt seem or sound like the bottom end as I have had two go out already on this car. First was the stock motor, she gave after 80,000 hard miles with over 300whp for most of its life. The second went out like two months after I had it built, lucky It was under warranty still "90 day warranty". SO now this is the thrid to go " if its blown" and second built by my builder and Ive only had this one for like 5 months or less. I wont be having a thrid one built by them, Im having my tuner build it this time if that turns out to be the case....... My prediction is Im gong to need a whole new motor!

Could be the tensioner failed..... Over or under torque the bolts on that and you're screwed.

black beast2 10-14-2011 06:35 PM

So the bolt that holds the timing belt tensioner snapped in half. Atleast all the valves are bent, the heads might be toast and not sure about the pistons yet. so basicly new motor time. the place that built the motor said it was just a freek happining and have never seen that bolt snap in half like that and are taking no responsabilty for it. Everybody esle says that that can only happen by someone over tourqing it. If thats the case do I have cause to go after the builder for compensation, or am I just burnt because its out of there 90 day warranty?

wagonracer 10-14-2011 07:03 PM

I would absolutely go after them, as they can't ethically just brush that off as a fluke. A 90 day warranty is pretty chickensh#t to begin with. Go get 'em !

psinuse 10-14-2011 07:12 PM

Well did you sign anything when you bought the motor from them or had them install it? Might want to read that over I really hate to say this, but I doubt they will do anything.

newtothegame 10-14-2011 07:27 PM

I hate to agree with Keith as it goes against you and all. But he is right, I have read and seen this happen before. But of course Cullen is absolutely right about ethics, but unfortunately alot of people these days can be shady and still sleep at nite.

psinuse 10-14-2011 08:29 PM

So agreeing with me is wrong...Oh I see how it is...*turns back on newtothegame* /sarcasm in case you missed it.

turmic 10-14-2011 10:26 PM

My tuner...even though I have great experiences with him. Everything is a "as-is warranty". Which is why they sub out the engine and transmission work. It will be under the other companies warranty at that point. But, my tuner doesn't go with crappy people to do the big work.

Haha, good one. I just dont like seeing the customer get crapped on. Been thru it myself, a couple times. But I did get the sarcasm...well played.
