not liking that plenum volume dude.. goes some way to explain the fuel trimming... You have email
Wheres the water come from in Dubai?..
Bad luck mate, but could cure other issues you've had too.....:icon_thumright:
its yellow
the Fastest Colour
So I had a low oil pressure alarm a week ago, I was very surprised as Main and rod bearing clearances were with in specs when I assembled the engine.
On cold start up the oil pressure was just above 4.5 bar at idle, then once oil was hot the pressure would sit around .8 bar at idle.
I changed the oil for some fresh stuff and the oil pressure was back to normal when hot.
So been driving the car gently while logging lambda control - been a few trips without any oil pressure alarms.
Did have a fault - camshaft to far retarded - Bill said its oil pressure related.
So I dropped the oil pan over the weekend to find a spun rod bearing on #1 cylinder
Crank has some light scoring,can barely feel the scouring with my finger. Rod on the other hand is not so good.
Looks like a new IE rod and oversized rod bearings plus engine strip down to clean the metal fillings out the engine.
I feel your pain as i've have been though that
I will be up and running soon. Have you measured the rod as it might be ok?
a ****!
really?
tang'd rods?
What make of shells?
lubed to feck on assembly with engine build paste etc?
that sux dude.. not what you wanted at all. Sorry to hear this
Rather disappointing day. Just wish there was something to point to that has caused this. Engine hasnt been revved, all clearances within spec, bolts torqued to ARP specs. The weird thing is the oil pressure was fine when hot then out of the blue driving slowing around a corner, the low oil pressure alarm sounded. There was no weird knocking noises from the engine at all. Cold start up had high oil pressure at idle and engine was quiet, warm engine had lowish oil pressure at idle and engine was still quiet, even with revving the engine.
Yip, tang'd rods, tang'd calico bearings, heaps of assembly fluid on all main and rod bearings.

check the oil filter housing, there's a pressure relief valve in there , I had a similar issue recently and Ben parsons suggested I check this out a I'd checked it out. Low and behold the valve was stuck open with a bit of crap and oil pressure wasn't getting up to its normal pressure. Fortunately I didn't spin a bearing but it was enough to damage the head. I'd never even thought of it so worth checking.
also didn't someone else on here have issues with 2 sets of calico bearings?
Do you mean you have double dowled the timing gear or the flywheel?
