csa Posted March 29, 2009 Share Posted March 29, 2009 hi guys This weekend I've installed my rebuild engine, but when turning it, it wont make oil pressure. I've taken off the oil feed to see when the oil gets through, but nothing is happening, and I think I've been on the starter for 7 mins in total (30 sec intervals). a few facts: *The oilpump is a PHR one and has been filled upon install. *The oilfilter was filled upon install *Oil is 15w40 mineral *Cilcooler has been removed and the lines ha been filled and connected *I've used 6,5 liters of oil in total *I've tried with and without the plugs in it (without coilpacks) I'm really starting to panic, what should I do next?

georigg Posted March 29, 2009 Share Posted March 29, 2009 Hi CSA, Not sure what your problem may be but trust you are "turning the engine over" without the spark plugs in? If you take them out then the engine will not be pressurising up each cylinder and putting a load on your new big end bearings. Also, after 7 minutes on the starter if you have no oil getting to the big ends you are very close to damaging them again!............especially if you left the plugs in! Did you do the rebuild or did someone else? If someone else, get in touch with them pronto - you have a problem! If you did it yourself are you confident you assembled the oil pan oil pick up pipe which delivers oil to the pump? ......located on the front of the crank. You need to stop and think through everything you did during the re-assembly and if you cant think of anything...........then another strip-down is on the cards..........at least taking off the sump and checking the whole oil route etc, etc., sump to pump pump to gallery etc. Best of luck!

I presume you made sure the O ring/seal was in place and tightened the oil pickup. Other than that it may be worth checking just to make sure there is a spring and valve in the pressure relief valve. I will mention that when i first got my PHR pump, it would not turn, and felt solid, so rather than risk it i rebuilt the pump. Other than that i can't think of anything else just now, but i'm sure somebody will be along with more suggestions. Quote Link to comment Share on other sites More sharing options...

George it's been turned about 5 mins with plugs and 2 without Quote Link to comment Share on other sites More sharing options...
absz Posted March 29, 2009 Share Posted March 29, 2009 did you prime the oil pump by pouring oil into it before fitting ? as sometimes IF fitted dry they don't pump. you can remove the oil pressure regulator nut and pour oil into it and try again.

JamieP Posted March 29, 2009 Share Posted March 29, 2009 Looking at your build thread he seemed to use a lot of sealant, could this have blocked the oil pump? Quote Link to comment Share on other sites More sharing options...

Lee P Posted March 29, 2009 Share Posted March 29, 2009 You wont get oil pressure with the PHR pump just turning it over the first time you start, I had the same problem with Wayne's. If you have an oil pressure gauge check it while trying to start the engine with everything connected, its not going to start first time anyway but as it tries you should see a bit of pressure.

Lee P Posted March 29, 2009 Share Posted March 29, 2009 If you still dont see any pressure at all when the engine is trying to start then you may have an issue, if the needle shows a little pressure then just fire it and you will be fine.

csa Posted March 29, 2009 Author Share Posted March 29, 2009 uhh that sounds terribly dangerous. How long should it be started, and should I do it with the turbo oil feed disconnected? (keep in mind that I've turned it quite a long time all ready) Quote Link to comment Share on other sites More sharing options...
Lee P Posted March 29, 2009 Share Posted March 29, 2009 No, just connect everything and turn the engine over. It wont start straight away but as the revs jump a bit you should see pressure on the gauge. If you do then you are ok to continue. If you still dont see anything at all then you may have an issue. When the engine actualy starts you will see full pressure straight away. Quote Link to comment Share on other sites More sharing options...
csa Posted March 29, 2009 Author Share Posted March 29, 2009 okay, but for the very first start up, how long should I have it fired upp until I SHOULD see pressure? Quote Link to comment Share on other sites More sharing options...
Lee P Posted March 29, 2009 Share Posted March 29, 2009 As I said it will not start first time anyway, but as it tries to start it will show pressure on the gauge, if it doesnt then dont let the engine run. Quote Link to comment Share on other sites More sharing options...
csa Posted March 29, 2009 Author Share Posted March 29, 2009 okay, will give it a go tomorrow then. thanks everyone! Quote Link to comment Share on other sites More sharing options...
absz Posted March 30, 2009 Share Posted March 30, 2009 When i rebuild my engine i cranked it over for about 20 secs at a time with 1min break in between about 4 times, unscrew the oil filter and there was plenty of oil coming out. this was with spark plugs removed and fuel disabled. reconnected everything and she fired up first time held the revs at 2k for the first 5 mins while someone looking around for leaks.

csa Posted March 30, 2009 Author Share Posted March 30, 2009 many thanks for all the replys. I got it sorted today by removing the camcovers and poured plenty of oil down there on both (to make sure cranking didn't harm the cams). Then I refilled the oilcooler hoses with quite a lot (over half a litre). the I cranked the engine witout the plugs in it for about 10sec, and BANG, oil gets out of the turbo feed. I installed the plugs and turbo feed and it made over 2 bar oilpress easily on the starter alone happy chap here :-) Quote Link to comment Share on other sites More sharing options...
