I had a look on the forums and found this problem but not where someone had just rebuilt the engine and put coolant in without starting. My first thought was the rear main seal, gasket or housing but then I read that it can also be from the intake manifold gasket.
Had just put in approx 9L coolant in and within minutes I noticed the dripping. One drip every 30 seconds by the look of it.
Rather than rip the whole thing out again is there an easy way to establish what it could be?
Used the Permaseal kits for the seals, gaskets etc supplied form the machining shop;
(1) Permaseal Conversion Set E2037KY
(2) Permaseal Regrind Set V2037KCU (found out later this is 1995-2001 maybe VT era. Permaseal said would be okay but the upper intake to lower intake gasket was different but I didn't need it as I had already bought the metal one from Holden).
Rear plate was checked and cleaned at machining shop and they put the rear seal in for me when they checked it. I used those plastic bolt mounting things that came with the rear main gasket set when putting the cover and bolts back on. Torqued to spec inc degrees and used medium strength thread locker.
Intake gasket ends used Loctite Blue Maxx on the four corners and thought I had lined up the intake gaskets perfectly.
Trying to figure out the best way to proceed as I'm still in learning stage for all this stuff. Any help would be greatly appreciated!
For now gonna go take the intake off I guess and just hope that's all it is. Should I be sucking some coolant out first or is it gonna be obvious when I get there that that's where it's leaking from?
Just to double check, when tightening the head bolts, follow the torque sequence but do NOT ever go above 90Nm. Stop tightening a bolt during the procedure if you hit 90Nm and finish with that bolt. Does that about sum it up?
