2ND timing belt. need some help

[Mr GTS4]

ok its coming up onto the 200,000k mark and the motor is still boosting fine and running great. now my friend said when he does the belt he wants to change the front crank seal and the cam seals aswell. first thing - do you have to do them? is it better if you do and secondly how much do they cost?

any help on the subject would be great.

Thanks

I'd do them and any other seal you can see at the same time. Its so much easier doing it when everythings apart then having to do them again if they start to leak which nearing your mileage they will start to do soon.....

cheers!

Also budget for a new waterpump and check the tension of the oil pump bolts while it's apart.

The seals are the same as the RB30/VL/R31 cam seals. (The oil pump also uses the same seal as the camshafts)

About $6.50 each.

If you want genuine you will pay around $15 each.

And as mentioned, do the water pump as well.

Im fairly sure the RB20 has the same pump bolt spacing as the local VL/R31. (The RB25 is different though)

Therfore you can get an aftermarket pump for around $88 (PowerMax brand - Made in Japan)

Genuine pump will be around $120.

Its a good idea to do the seals as they go hard overtime and score the crank and camshafts, this is what causes leaks on high km motors. To do the oil pump seal, you would have to remove the crank timing gear, which is a real bitch, often you have to split them and get a new one in order not to damage the oil pump ($49 for a new timing gear).

You should be able to do the oil pump seal without removing the pump itself. If you remove the oil pump, you have to drop the sump.

Hope that helps some.

[Mr GTS4]

cool. well i don't need a new water pump as i had one installed not long ago.. so with the crank seal thats the same as the rb30/R31/vl and what about the cam seals? same as all the other twin cam rb's

thanks for you input guys!

[RB30-POWER]

The cams use the same seals as the oil pump

[Mr GTS4]

say do i just ask for oil pump seals? do they more than 1? never really looked at a oil pump so i don't really know.

[RB30-POWER]

There is only 1 seal for the oil pump.

I have a timing belt in the for sale section 'Brand new' for $100 its a donation sale aswell...

[Mr GTS4]

i bought a gates racing one for $91. thanks but yeah. anyone know the answer about using oil pump seals for the cams?

Just get genuine ones. You'll thank me later. If you go aftermarket you compromise quality with THIS particular product. Trust me I've been there. Three times now.

It's only a few dollars more and you can just give Nissan you VIN and tell them what you want.

The other thing is, when and where is your mate doing these seals. I wanna come and watch to see how he'll get the lower timing belt pulley off to get at the seal. With that particular seal, make sure you have all the equipment to remove it properly before starting coz if you don't, chances are you'll wreck something. Unless you know for sure that it will come off easily. I only say this coz usually it takes an oxy, a couple of big levers, a big hammer, a grinder, a claw puller, a brand new pulley in the end and every swear word you and your mate knows to get it. Let's just say that the neigbours will learn a few new ones. lol.

Good luck.

[Mr GTS4]

umm..... well.. i think i might just ask him if he knows what he's into.. he is a very knowledgable person that works in the industry but hasn't worked on a rb but everything else. lol... neigbours.. who needs em lol

[The Dan]

hehe yeah. I only remembered how hard it was yesterday coz I had to remove one from a second block I have to get the crank out. I should have mentioned it earlier, I've done enough of them by now.
