Changing Front Seal On Rb26

hey guys,

Got a oil leak on the front of the motor around the oil pump and all up the face of the block. At the moment it looks like the cam covers leaking oil and running down the front of the motor(am in progress on changing them now)and filling up the cupped area on the pump. BUT im also thinking it maybe the front seal as well. How hard it it to change or is it worth just putting it into the motor mechanics and getting them to do it if it still leaks after fixing cam gaskets.

you'd wanna make sure it was actually leaking and at a rate that bothers you before you go to all the effort.

if you know your way around the engine bay all you need are some tools and engine manual (pm me if you need a copy) and you should be fine.

got no problems with doing the work, only thing is getting the harmonic balancer off but can make something at work to do that.

pretty sure is the cam covers making the mess as was alot of oil down the side of the block and think some has been sucked behind the timing cover by the looks. belt was changed about 50k ago so half way through its life.

will have a look at the cam seals tomorrow but dont think they are the problem either.

I have a manual as well, thanks for the offer anyway :thumbsup:.

not sure if ur aware of it mate but the allan key bolts from the cam cover match the thread of the two holes in the balancer. So if u end up making some sort of puller u can use those by just throwing some washers on the end of them. Though depending on how tight ur balancer is on there u may end up stretching the cam cover bolts so try get a hold of some yeild and spray the hell out of it....

Radiator will have to come out if ur goin to use a puller so u got some room....

thanks for the heads up Joe, will get some ss or high tensile ones from work.

got the motor back together now, just seeing if the oil will subside otherwise will pull the front down.

how hard it the bottom timing belt gear to get off??

already been to nissan and got the part number, cost about $31 i think. such alot of work for a little part >_<

they vary a lot. i pulled my rb25 timing gear off with my fingers, just slid straight off. then i needed a grinder to get the rb30 gear off, was fused to the crank. if its that bad you can try drilling and tapping it for a puller or you can cut it off like i did and use another one. i have a spare if you destroy yours :pirate:

Gunna have another look tomorrow to see if the cam seals are gone. Oil seems to be still coming from high up ( clear cam cover ). So going to remove top and bottom cover, clean everything, connect everything up and run it to see where its coming from.

Wouldn't think it would go above gasket line. Maybe I'm wrong

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
