i bought a newly imported rb25det about a week ago, the bloke i bought it off said i needed to reseal the sump, to do this do i need a casket or something else?

i don't have an engine hoist, and the engine is sitting on the sump now so i can't take it off to have a look..

Cheers, Matt..

Yes, the sump will need to come off, and clean both the sump and block mating surfaces if they still have parts of the factory sealant or oil contamination.

You can either by the original sealant from Nissan, or just go to any parts store and purchase a suitable gasket sealant maker.

Its vital that the two parts have a good complete seal.

Cheers, the bloke i bought it off has cleaned it as a part of the import process, he said i just had to re-seal it, i'll go off to nissan and get some sealant then..

thanks for the help..

nissan wont sell you selant. they might have a gasket for it though..

but just head down to supercheap or repco and get some gasket maker. its a type of goo that dries into a rubbery material. make sure your mating surfaces are clean.. he wouldnt have cleaned them himself otherwise he would've sealed it himself and charged more for the motor.

Yes nissan do a "liquid gasket sump gasket"

When i asked for a gasket for an RB30 a few years back, they said, no gasket only the genuine Nissan "liquid gasket sump gasket"

From that point, i just went to local auto parts shop and purchased gasket maker as its cheaper.

But if you want the factory sealant, you can easily get it through Nissan.

I can honestly say I've never actually seen an RB sump gasket, only the sealant. Sounds like you need to borrow a floor crane and engine stand. The lower bell housing brackets will need to come off the block to get to all the bolts for the sump. A seal breaker may be needed but I just knock a scraper blade in and remove with pliers until I get a fair bit of seal cracked. Once off give it a good clean and degrease. To remove the sealant from the sump the best thing is a wire wheel on a bench grinder. A scraper is good for the block but be careful not to drop any sealant in. Also look closely at the oilo film in the sump for any gold flakes which can indicate bearings nearing life end.

While it is apart whip off the flywheel and replace the rear main seal and the front seal in the oil pump if the harmonic balancer comes off easily. Cheap items but hard to do in the car. RB30 items are cheap and fit and easily acquired.

Sealant I use is just the blue stuff from Autobarn.

    • After @Kinkstaah debacle, I'd never want to try and get it right 😛
    • The hood lines up with the fenders. The front bar doesn't perfectly line up with the fenders where the wheel arch is. You have to 'squeeze' the front bar 'in' as it wants to naturally flare out and be longer on the sides. There's a few threads where people notice this when they only swap a GTR style bumper and front bar. Unless you have genuine OEM items - you may be better served getting conversion kits. There are GTT bumpers to fit GTR hoods. There are GTR hoods (non genuine) to fit the GTT bracketry. MAY  
    • The real question is, on some of those wild roads they call highways, how many times did a farmer in an old ute from the early 2000s blaze past you over double lines?   Tassie is a wild and really cool place, and after doing a work related road trip there January of 24, I understand why Targa Tasmania is ran there, and is so tough to do well at! We had a brand new Camry Hybrid that handled quite nicely, and thankfully weren't in an old car, because cresting some of those hills in a 100kmh zone for it to suddenly be like "surprise f**kers, this is a recommended 30kmh hard right turn" wouldn't be pretty. We weren't racing the Camry around, but we weren't slouching in the bends either. But my lord those old farmers know their old clapped out utes, and those roads, as they were absolutely hammering it!   You're also super lucky to make it up to Mt Wellingtong this time of year. It's often road closed with snow/ice! Also, I hope you hit up Salamander Road in Hobart for some insanely good food (I highly recommend the dimly lit Irish pub for a Guiness Pie, or even the bangers and mash!!!)   How long did the Ferry take to get across? I want to do a road trip of Tas on my own time, but I get horrifically sea sick, and I don't want me on the Ferry, just the car 😛
    • So far so good, about 30km on it so far and nothing out of sorts yet thankfully
    • Look at @Kinkstaah's thread on the issue.
