I noticed white smoke coming out of my tail pipe at startup just out of the passenger side it smelt like antifreeze. I have noticed water missing from my radiator and have been refilling it and the truck runs fine. Well to make a long story short I took my spark plugs out and turned the engine over and water is coming out my #7 and #8 cylinders sparkplug holes more out of 8 than 7.
I did the normal trouble shooting

the facts

no water in oil oil looks good
antifreeze smell in exhaust
engine has about 2500 miles on it
I did not retorque my heads

What are the likely hood of it just being the intake manifold gasket?
what the chance of both head gaskets blowing?

NAW... IF YOU ONLY HAVE 2500 MILES ON THE MOTOR, I KINDA DOUBT IT IS MORE THAN A HEAD GASKET OR INTAKE GASKET, OR BOTH. I DON'T KNOW WHAT KIND OF GASKETS YOU USED, BUT I LIKE TO USE FEL-PRO GASKETS. THE HEAD GASKETS ARE CALLED PERMA-TORQUE GASKETS & NEVER NEED RETORQUING. THE FIRST THING I WOULD TRY IS GASKETS. (THE SIDE WITH THE BLUE STRIPE GOES UP) JOHN

I'm surprised it's not over heating. Yup, head gasket because there is no water flow through and around the intake manifold.

nothing like the sweet smell of antifreeze in the exhaust.......

qksilver · 01-09-2006, 11:20 PM

Could be a few things, pull the head and there will be your answer

case_bt · 01-10-2006, 01:03 AM

after pulling the distributor and intake I was getting water in my oil nice yellow like mixture pulled the head off # 8 had water in it. Would you think the rings would be ok? before i pulled the head off I checked compression it was like 120-130 psi. heres some pics for you guys. this was my first engine to build and it won't be the last.

**truckdude239** · 01-10-2006, 01:13 AM

rings should be fine now just check the deck and the face of the heads and block make sure everything square. install new head gaskets and get the intake gasket on good and put her back together and hope eveything goes okay

case_bt · 01-10-2006, 01:15 AM

could i get some suggestions on what type of head gasket to buy I don't want crap and install tips would be great.

**truckdude239** · 01-10-2006, 08:38 AM

perma-torque gaskets by fel-pro are good gaskets

Good advice

muddbugg72 · 01-10-2006, 12:43 PM

be sure to put thread sealer on all of your head bolts. they all go to the water jacket. hope you get it going.

case_bt · 01-10-2006, 02:55 PM

what bore size gasket do i get my truck is 40 over they have different sizes

case_bt · 01-10-2006, 06:18 PM

with the felpro do i install them dry

cdyblu · 01-10-2006, 06:29 PM

Go Fel-Pro all the way, they are the only gaskets I use. Never had a problem in well over 100 engines

case_bt · 01-10-2006, 06:46 PM

does anyone know what size bore gaskets to use my truck is 40 over but felpro has lots of different bore sizes?answered it myself part # 1003 they are good to 4.155 bore size

junkyardjohn · 01-10-2006, 08:40 PM

CASE... I'VE REBUILT MORE THAN A FEW MOTORS, & ONE LITTLE THING I ALWAYS DO IS USE FEL-PRO GASKETS. THEY ARE NOT THE CHEAPEST GASKETS YOU CAN BUY, BUT THATS OK... YOU DON'T WANT THE CHEAPEST ONES YOU CAN GET. ANOTHER LITTLE TIP IS SPRAYING BOTH SIDES OF THE HEAD GASKET WITH A COPPER HIGH-TAC & SEALANT PAINT (SEE PIC.) . JUST SPRAY IT ON BOTH SIDES & LET IT TAC UP FOR 4 OR 5 MINUTES BEFORE YOU INSTALL THEM. THIS REALLY SEALS EM UP & MAKES THEM STICK LIKE SH!T TO A BLANKET.

case_bt · 01-10-2006, 10:36 PM

the perma torque I bought said they need no sealant

junkyardjohn · 01-10-2006, 11:17 PM
