Blown 4.0

Damo · 09-11-2005, 08:39 PM

... and not in the good sence.

Tonight I went for a drive up the street in my EB to get some things. I was getting along pretty quick revved out second and went to fourth when I hear this god awful BANG!! CHINK! CHINK! and the car stalled. Pulled over to the side of the road and had a look under the car etc, all looked fine.

So I walk back up the road about 40 metres and see a few chunks of metal and a bolt sitting in the middle of the road. Ohh crap. Go back to the car and have a look under the bonnet. I've blown a BIG chunk out of my timing case and the chain is exposed. :( I guess you could say 'I did a Sunny' looked almost identical to what happened to his motor not good. Tried to start it but no luck it just cranks and cranks but won't fire.

I've got no idea what happened to cause it, maybe the timing chain had skipped some teeth or something, no idea really.

So now i'm gunna have to get it towed home tommorrow, and I guess i'll be replacing the motor sooner than I though. Just need to save up some more moolah so I can get an EL motor or maybe get a semi reco one from John XR6.

So that's been my not soo great evening. I'll post up some pics tommorrow when I get it home. :gren:

EFFalcon · 09-11-2005, 08:48 PM

damn, that was sudden.
sounds like what my oringinal engine did :|

LUXO_8 · 09-11-2005, 08:51 PM

i hope my current engine doesnt do this on me..... although it will be more rod out of block stylez if it does lol....

damn hey....

09-11-2005, 08:56 PM

that really sucks damo! but you know i have an ED XR bottem end there already honed out ;) just needs gaskets, bearings and rings....

Dezza · 09-11-2005, 08:59 PM

Sounds nasty. You haven't had the EB long either, have you?

oneredED · 09-11-2005, 09:03 PM

Oh DAMN!!! I am bad luck man, I shouldnt have visited today :P So sorry to hear that though man :(

EASPRINT · 09-11-2005, 09:09 PM

Damo...have a look and see if the PCV Valve is still in one piece.....i've seen the ball fall out and drop into timing chain before.

Damo · 09-11-2005, 09:12 PM

yes it's deffinately your fault Jared. :P Heh, i'm not too worried about it I still have the EA to drive around while I save up a bit.

ea silver ghia - Nah I've only had it a couple of months, blown the clutch and now the motor, although the motor was pretty tired anyways, I'm just at a loss as to why it happened.

Oh well sh*t happens.

**Polyal** · 09-11-2005, 09:13 PM

ah that sucks.....

If my motor goes (it shouldn't) I would look at getting a crappy 2nd hand one then getting it reco-ed, or even try doing it myself. A stright swap with a 2nd hand motor seems like a waste.

Hope it all gets fixed quick.

EASPRINT · 09-11-2005, 09:20 PM

I've seen a 4.0 smash the timing cover to pieces...all because of the PCV valve...

EFFalcon · 09-11-2005, 09:23 PM

LPG Back fire cause PCV to break, ball bearing in PCV finds its way into timing case, obstruction in timing case smashes open timing case.

Yeah...and i've also seen a rebuilt performance engine let go in under a week

:...but ...i wont comment on that.

niko · 09-11-2005, 09:29 PM

stop bagging gas, i dont see any signs of this "blown" motor to be on gas!

Damo · 09-11-2005, 09:45 PM

My car is on Gas Nik, it just doesnt have a tank.

: I'll pull the rocker cover off tommorrow night and see if I can suss out what may have happened.

Polyal, I don't think it would be a waste to put in a Low km EL engine, i'm surprised my motor has had it allready only done 270,000 k's. Still ran a flat 16 a couple of weeks back.

Stevo · 09-11-2005, 10:00 PM

the gas made it go ka-bang! fricken gas!

on a serious note, thats a real bummer damo. Hope ya get it up and running again for the next cruises.

Steve

-jjM- · 09-11-2005, 10:22 PM

thats some really bad news dam, weve had 3 blown heads over here, all to firmiular wit it too

terrible news, hope it dont think ur pocket to much mate

*goes and huges my motor*

Damo · 09-11-2005, 11:03 PM

lol ^^ damn you XR motor boy.

should be up and running again before GOR, but i'm not aloud to bring my car to that meet apparently. :P Then again It might not be unless I can pick up some more hours at work. Damn stooges.

Sundeep · 10-11-2005, 02:11 PM

Sounds exactly the same as mine Damo! If the chain still has tension it will be a seized dizzy shaft most likely. How was the oil level?

Yeah I think that was a recall on EL's or something, they replaced all the metal PCV's with plastic ones after that.

EFFalcon · 10-11-2005, 02:56 PM

wouldn't be the other way, replace plastic ones with metal ones so they can't be broken?

DUMTEF · 10-11-2005, 03:00 PM

yay go e-series cars!!! :thebirds:

:

Damo · 10-11-2005, 05:01 PM

yeah the chain still seems to have tension Sunny. Got the car towed home after work.

here's a couple of pics of the carnage.

TURBO_GHIA · 05-01-2006, 02:59 PM

hey mate mines done sort of the same thing ,its done the aux gear but didnt blow chunks of the timing case apart,did you fiddle with the engine before it went ,do you have an aftermarket cam in it ??

Yeha apparently it has a crow cam, i've pulled that out now and need to confirm it is a crowcam so i can sell it. I didn't fiddle with the motor at all, but it was pretty worn anyways and blew a fairbit of smoke on startup.

gthofan · 05-01-2006, 03:09 PM

you say lpg can backfire and cause the pcv valve to break :(, do i have anything to worry about in my ea which is on gas, and is there a way to convert to a metal valve if it is plastic??

TURBO_GHIA · 05-01-2006, 03:11 PM

if you have a plastic one go and buy a metal one there like $10

gthofan · 05-01-2006, 03:14 PM

oh well that is easy, to check do i just pull it out of the rocker cover???

TURBO_GHIA · 05-01-2006, 03:18 PM

um yeah it should just pull out

BOOSTDEF · 05-01-2006, 07:03 PM

timing chain may have come loose?? id say its not starting as your cam will now be out with the crank?? just a guess.. i had the same thing happen to a datto once.. but i suppose we are talking real cars now so i dunno.. hard luck mate. Still no chance in starting it?

Damo · 05-01-2006, 07:43 PM

hahah ^^ did you looks at the date of this thread.

The chain still had tension, but the aux shaft is way outta wack, which somehow forced the chain off and to bust into the timing case. I'm swapping the motor this weekend anyways.
