Re: RRC EFI 3,9 oil pump priming issue

News: After connecting the 2 hoses of the oil radiator, and bleeding what air I could, I managed to get a pressure of 30 psi at 2000 rpm on my drill. This seems very correct to me. I get this pressure after about ten seconds. The resistance on the drill is not very high (I thought I read that it was...

Re: RRC EFI 3,9 oil pump priming issue

I added 4 liters of oil, still nothing...it only comes out through the intercooler connection. I'm going to remove the relief valve and try again... I wonder if an air leak at the feet of the rocker arm shaft (deformation / very malleable aluminum), the oil circulating there, could be the source of ...

Re: RRC EFI 3,9 oil pump priming issue

I mentioned oil comes through this side...The question is why i have no oil at all on the pressure sensor side.

RRC EFI 3,9 oil pump priming issue

Hi, Going forward with my rebuild (new cam and lifters) i'm stuck with my oil pump. I checked clearance and gasket thickness before setting. I tried to prime with an electric drill...without success. i have pressure on the oil cooler exit (i put a bypass valve) so i imagine the sump filter is ok. Bu...

Re: Range EFI 3.9 front cover oil seal

Manual says : Press in the oil seal until the plain face is 1.5mm below the gear cover face. Mine is just at the same level as i use a wooden block, and not a press. If i do more i fear to damage the face. Is it important to go 1,5 mm furthur ?

Re: Range EFI 3.9 front cover oil seal

OK i keep only one on my cover. I put the older one but in good shape.
The inner lip is good as the spring. The outer lip (photo) is a little damaged but it doesn't matter for the seal efficiency...
Agree?

Re: Range EFI 3.9 front cover oil seal

In fact, I fear that the frame will be slightly deformed, although I used a wooden block... In short, either I remove the 2 seals to put a new one in, or I leave it like that with the probability that the 2nd one will disintegrate over time between the 1st seal and the protection plate (n°3 in the d...

Re: Range EFI 3.9 front cover oil seal

I just wonder if i can put the two seals side to side. I have enough room for this. If the first one is leaking, the second one protect...am i right?

Range EFI 3.9 front cover oil seal

Hi,
Remove the old seal...looks quite good. Any more i put a new one but not seems to be perfectly "watertight".
Finally, I decided to put side to side the 2 seals, in case the new one is not 100% good .
Any suggestions ?
