Water in sump, EA82's rust out welch plugs?
Posted: Sat Jul 16, 2011 6:03 pm
QUESTIONS are:
anyone ever have EA82 do this
anyone know for sure EA82 had and always had stainless welch plugs
Got all my swearing out of the way for a while......
After renewing:
a] water pump to heater hose metal pipe
b] water pump to radiator metal pipe
c] all spider inlet gaskets - one side loose and was bleeding towards inlets
d] a no- pressure-holding radiator cap
and bypassing the throttle body anti ice hoses, I finally got to pour water into my EA82T, let it settle and bubble up air, and again, and again and again!!
Getting a bit suss as I left water in my radiator fill funnel to work its way into nooks and crannys to avoid any air locks, I pull oil dip stick out to find sump has a far greater volume of oil level that I put in about 15 mins use time ago.
I did not even add pressure to radiator just atmo. The PO mechanic likely added his pressure tester to the radiator , arriving at blown HG diagnosis. Given that the radiator cap was not pressurising the system for a while, some presure from a tester at 15 psi likely helped test the rusted out pipes and leaking gasjets I have found and replaced. Even though a car may be going well before a radiator presure test does not mean it will be driveable after the test.
Not even gonna try and run this baby with water in sump - at least at the moment it is separate, no need to add pressure and turn it into buttermilk.
"talking" to Neville nncoolg and after some thinking went on, the suggestion of welch plugs in the head was made, allowing a bucket load of my tank water to fill the sump. I undid sump lug armed with two drain dishes in case and got a few litres shall we say, of crystal clear tank water, and as that came to an end came out with a top deck of engine oil.
Good way to check before I add more oil to the sump is pull rocker covers off and fill radiator to see if Niagara starts up either side
Bought this car as a goer with diagnosis of blown HG's. My anal aproach to a problem like this is to replace the easier, simpler , cheaper stuff first and test as I go, rather than jump into it. My compression test came up 160 psi +/-5, and cylinder leakge test came up pretty good for an engine its age and definitely did not leak like this into water jacket.
Reckon due to corrosion levels of stuff found so far it is HG or maybe Nevilles easier suggestion of welch plug. Engine out either way.
Head gaskets commonly go between cylinder to cylinder, cylinder to water, cylinder and oil and I guess this time it could well be water to sump - evading the testing I have done so far.
