antifreeze leak at starter?

[racer55]

Ok there are frost plugs in the rear of the bell housing area behind the flywheel,the block off plates are where the rear engine ground wire stud is and the mounts for the glow plug relay on the other side.
They are separate from the intake manifold and cover ports on the rear valley side of each cylinder head.

Thank you....I will look again

I think it is coming from main seal...nothing on dipstick and I dropped the inspection plate enough to see in there. I used a dye light and saw green around the rear main seal....I guess I will have to drain the oil and see...

Well drained oil nothing there in oil or at the rear block off plates....pita this is...I think after all the vids and testing....i guess a replacement is the key here...I was hoping after getting this I could drive it till it gets warm

the valley drain would deposit antifreeze on the seal

I know...I looked everywhere and everything is dry. If you look at the videos then I think the engine has to come out anyhow. Maybe I will see it then....

Just confuses me I tried using a pressure pump....had it up to 17 psi and no leak anywhere...it only does it after it warms up...

Something is expanding and when up to temp boils most of the coolant away,I would spend my time checking the heater hose quick connect fitting on the water crossover,they are notorious for failing.

what's the pressure when running?

I did...I have a special light that shows antifreeze in the dark......It only shows up at starter,crossover,back of oil pan

here is what I suspect, headgasket failure is putting excess pressure in your cooling system causing leaks that won't leak under normal pressures. which might also indicate a cap that doesn't work anymore also

I put in a new therostat and replaced the tad cap

Update

I am going to replace motor. Maybe then I can see where my leak is coming from.

i haven't seen any vids, can you post a link? i think it might be heater core or head gasket. replacing with used engine is a gamble. rebuild will cost more than truck is worth unless you plan on keeping for 10 years. easier to replace gaskets, cheaper and quicker.

 

[hereismylife]

I fixed the problem. I replaced the engine. No more leak

 

[deejaaa]

where was it?

where was it?

Never looked...replaced engine since blowby and needed head gaskets. 100 hours later n truck has new engine
