!!!!Big problems with new motor that came from no where!!!!!

**WICKEDLS1** · 12-21-2012, 05:26 AM

Well after i got done christmas shopping and was headed back to work, i started it up it made a weird noise then started bellowing smoke out of the exhaust.
(mods to car in sig) first thing to go through my head was a blown head gasket due to the color of the smoke, however it doesnt have the sweet smell that coolant ususally
does when it gets burnt. not to mention i allowed it to cool down and checked the radiator and it was completely full of fluid. Well i babied it back to work so that i wasnt stranded, along the way it started popping and backfiring along with missing and pouring tons of smoke. (i couldn't see the car behind me it was so bad). Any ways i started it to try and move it after it sat the rest of the day at my work and it went straight to redline with no hesitation. i shut it off immediatly and haven't touched it since.

any ideas on what this could be? needless to say im not happy that my BRAND FREAKING NEW MOTOR MIGHT BE TOAST!!!!!

any and all help would be greatly appreciated

edit: this new motor hasn't had any power adders on it yet just an fyi

Um wasn't that a USED block you bought from Craig? Did you guys rebuild it or just throw it in?

Pull the valve covers and check from a broken spring. What does the oil look like?

**WICKEDLS1** · 12-21-2012, 05:55 AM

New bearings, rings and seals completely gone through

Thats what I was initially thinking.

Just pull the valve covers off first. Might be simplier.

Yes. Are those new valve springs or the leftover stuff from the motor that came with the car?

There the springs that were on the other motor, but dual spring .650's with titanium retainers so I dont see how this cam would have broken them but its worth checking

Does your map have a loose fit in the intake or is it a good tight seal? Gone nuts trying to get them to seal in the past on 90s. Just an idea before you yank the engine out.

**WICKEDLS1** · 12-21-2012, 05:00 PM

its pretty tight from what i can tell by feeling it but ill check it again tomorrow when i get up to the shop

**2002ssslp** · 12-21-2012, 05:07 PM

Did you stager the piston ring end gaps or put them in straight up and down ?

**Froy76** · 12-22-2012, 10:00 PM

A leaking injector or fuel pressure regulator can fill the intake port. Then hydrolock a cylinder, that would cause the noise. It will also raise the oil level and cause it to smoke. If the gas gets in the exhaust system it will also smoke. Look for easy fix first.

Springs can weaken with age. Sometimes things just break unexpectedly

Any updates Brendan?

Sorry been gone for a while but the problem was WAY worse then though but not as bad as it could have possible been

turned out the last rocker arm on the passenger side head broke completely out, heads were ported MASSIVELY and it was paper thin in that area so it was a matter of time i guess

called a buddy that welds aluminum to see if it was fixable and he said it was too thin and would just melt through so i just scrapped them and sold the titanium valves that were in them.
luckily i had a pair of 241 heads sitting around so i just swapped the valve springs and retainers and put it all back together then sold the damn thing. tired of messing with it and need to spend money elsewhere on more important things like saving for a house etc..

Took a nice little chunk out didn't it... Sorry you decided to sell it. But, sometimes other things are more important.
