When I was building new motor , I didnt ck block heater and after installing motor it was leaking or more like seeping .

I understand that he should check it, but I don't believe this motor went to a machine shop and since he didn't have the bottom end apart I doubt he even touched it. Even more so if it wasn't leaking before chances are it is still sealed up okay. In the end I guess anything is possible.

When you push a head gasket , looking for anything else possible is always good advise to give . Where he describes it leaking is low on motor . My guess is also it is leaking from between head and block and the trail isnt being seen from higher up on block .

Since when are you so pessimistic to other possibilities . Motor doesnt have to go to machine shop to leak here . Have you ever pulled one out Josh . They are lame design and can leak without going to machine shop . Could be a freeze plug also .

I think everybody would agree that most likely it would be stretched head bolts . My pushed head leaked out pass side between head and block .

He doesn't have head bolts Jon. And I am not saying it cannot leak from there, but you stated maybe the machine shop didn't reinstall it properly...that cannot be the case here as no machine shop touched it. Try not to put words in my mouth

No thats not what I stated , I said on mine the machine shop left it loose .

Why dont you read my post better . :buttkick:

Again block heaters are a lame design if you look at one out , and I have seen stock trucks leak here also . Especially when the motor sits without coolant in it . The o-ring can dry out . They can also leak through the little screw that expands the bars inside block heater .

Head bolts on stock motor .... studs ... on after market . Whatever . I again was stating why mine leaked there from stretched head bolts .

I was again giving the reason stock bolts stretch from high cylinder pressure on big tunes and again what happend on my motor . This is just knowlegde being passed on . And alternative things to look for like block heater or freeze plug . Could be numerous other things and I hope for his sake it isnt a head gasket . But most likely is .

I agree that this should be attended to before just running the truck and just adding coolant . If the head is leaking , the danger is it fills the cylinder when engine off and bleeds radiator pressure with fluid into cylinder , and then gets cranked and hydrolics and bends a rod or something .

When my motor was leaking like this , it did not blow out the coolant tank at all . It did let out just a little puff then clean up in morning start up .

After just doing the work done I would agree that it is most likely it is a head gasket leaking .

Im not putting words in your mouth . I do know a few things that would fit there though . :mommy:

Its nowhere near the blockk heater, motor was never fully drained of coolant as the bottom end was never ripped out and such. It sat out of the truck for just a couple days.

I tried sourcing it further upstream (headgasket) but had no luck. After chatting with a guy and a few others they doubted the head gasket unless I forgot to tighten a couple head bolts.

There is two things it has to be, either the rear cover is leaking or the headgasket is. We could go through the work of getting down to the head bolts and putting them through one more torque sequence but with time short and it not being 100% confirmed it is the headgasket we will leave it for now.

If you have any other ways for me to check the headgasket then simply lookin gat coolant running down the block please let me know, but wouldnt there be other obvious signs such as milky oil and wouldnt i see a little something in the exhaust??

I may do a compression test, we will only run it with this leak for the one hook then diagnose it further. Ive got so much money invested into this one time hook its ridiculous, kinda second guessing myself, but I cant get any of the money back so were going down and making a hook.

If something goes boom, its an excuse to build it better. And I always have a spare motor.

I didnt think about the rear plate leaking , that is another good possibility .

Seem that on a truck after install also . Is it more towards the rear of the motor ?

Would it be possible for you to post a pic of area involved .

I wish you best of luck on it .

Johnny

And Josh you know I am just jacking around with you and no offence meant .

Ill describe it as I dont have a pic right now.

On the passenger side motor at the very rear of the block where the rearhousing connects to the block, in that gap is where it is sorta coming from. Now when you look there you will see a plate with two bolts holding it on. Next to that there is a bulge in the block that runs the length of the block. Iside is where the oil runs that feeds the oil to the piston oil squirters. Now right on that bulge is where we see the drips coming out but it could be an illusion of something coming down from further up the block.

I am grabbing the blacklight leak test system from work today to try and find it.

That plate with the 2 bolts you are referring to is known to leak. It's usually hard to see with the exhaust in place.

I have the downpipe off now. I swung by the stealer and got some Dexcool tracer dye. And picked up a blacklight bulb at the hardware store. Well be checking it tomorrow night.

Thansk for pointing out that its known to leak though john, much more reassuring that I just need that little gasket. The truth will be told tomorrow night.

Sounds like it might just be something minor leaking back there . Thats a good sign hearing that they leak right there alot . I havnt seen any there , but thats why the web is cool . Everyone has some good info and experienced different things .

well the dye didnt work too good and the exhaust was killing our eyes and lungs. But we did come to a consesis that it wasnt the headgasket and is the rear housing.

However is there another test I could do to be 100% positive it is not the headgasket.

i suppose I could try that, but get this, we fire it up this morning, it leaks, but then all of a sudden stops and hasnt done it since.

Well keep an eye on it.

The plate on the ear adapter in the lower right is common to leak and look like a right side head gasket leak.
