**WARNING** LONG WINDED RAMBLE FOLLOWS!!
Hi all, Just spent the last 30 mins or so searching the forum, and now I think I know what I'm on about.... so here goes!!
Got sick of oily leaks in my R33 GTR engine, so started pulling it apart to change the rocker cover seals, which led to me pulling the cambelt out again as there is oil residue down thar.... :|
So now I've replaced the camshaft front oil seals - despite having it all apart once before, you think for the sake of small change I would have done it the first time.... http://www.gtr.co.uk/forum/86482-r33-gtr-cambelt-change-oily.html?highlight=water+pump :chairshot
Yep! I replaced the front crank seal originally, but not the camshaft seals - despite being a) cheap and b) apparently the same part # as the crank seal!!!! doh....
Now, down the turbo/exhaust side of the motor there is a lot of seeped oil, which I assumed to be the rocker cover seals gone hard with heat (still appears to be the case!) and possibly the powersteer pump line fuming oil too... tho having said that there is a lot of oil evidence around the oil pump on the exhaust side, but I'm not about to pull the motor to change the pump and that's a whole other argument!!!!
SO. On to my actual question!! I thought "lesson learned the first time" - while it's all apart, lets change the water pump. I won't go into the number of kidney's people here require for N1 genuine pumps - and speaking to Rob @ R.I.P.S today (thoroughly nice chap!) I don't require an N1 pump for a mostly standard road car anyway. So Nissan can do me a genuine stock pump for a reasonable price.
In the workshop tonight, I'm looking at the motor about to rip the old pump off, and thought "hmmm. there has been a lot of stuff replaced on this motor and car while it was owned in Japan, so how does one tell if a waterpump is standard or N1?" - cos the gasket sealant around the pump mating surface that has squeezed out looks non-factory, as if someone has already replaced the pump!
Which led me to my 30-odd minute search of the forum and the intertubes in general - and as far as I can tell the standard pumps have all round bolt holes, and the N1 pump has the slot for the small bolt on the top, near the impeller.... which my pump does have!!
SO. in summary, do I have an N1 pump (with the slot) as it would appear, or are there other, standard (non-N1) pumps with this slot? Is there any other way to identify standard vs N1 waterpumps? I cannot see any numbers or other stampings that I could use to ID it.....
Thanks for reading, and I look forward to someone in the know setting me right (or wrong!)
