Nitto's new slogan for their oil pumps.... "Engineered to pump engine components... not just oil!"

interesting.. when we pulled my motor down for a freshen up, we found all 6 cam cover baffle bolts from one side in the sump. Amazingly they seem to have done no serious damage to anything (some marks on one of the cam shafts, but engineers have pronounced it fine.

Wonder how commonly this happens.

what do cam cover baffle bolts have anything to do with what you just said? *im confused*

"The workshop that built the motor removed that mesh filter and ran a straight pipe. I have no idea why"

please explain?

from what i heard it was advised that the sump/pickup was of a very inferior design and was a reason for previous failures, and it should not be used..this was disregarded, the "filter" i was told had nothing in it and was simply replaced with a -12 hose. since an empty filter housing will not filter and can create a restriction.

unfortunatly at the end of the day, if the sump and or pick up was "allowed" to be modified to the standards of the workshop in question, this would still be going..

also a picture of the oil pickup installed in the sump will explain allot to those people who are struggling to grasp the nature of the failure.

im sure the workshop who built the motor would of not installed the rocker covers with bolts broken off. it almost sounds that you are insinuating sabotage? mayby someone pulled the covers of, broke the heads of and then added them later at an oil change? please..

i get the impression that this is a very one sided debate with not all the facts out on the table. like i said. a picture is 1000 words.

      Which are almost all nonsense. Ignore. Obviously enough, if it is not a porous block, then any such thing is a waste of time. External block surface? Would be a waste of time, if the block was actually porous. It would need to go on the inside, which is inaccessible, and even if the block was open deck so that that area was acessible, it would be unlikely to work. But seeing as this is all nonsense, stop worrying about it.   If the coolant is coming from the side of the block it is 10:1 odds that it is either a welch plug, or it is coming from the head gasket. Maybe from one of the coolant lines feeding the turbo, or even the heater. Liquids that leak from up high can travel sideways along casting surfaces or pipes, etc on the engine before finding a spot from which to drop.

      Yeah rust is sadly also a bit of an issue on my car. Doubt there is many cars out there that actually have no rust in those aeas. The strut towers look fine but some of the surounding metal sheets show a bit of brown cancer peeking out from in between. I hope I can make do with external remedies and won't have to rip open the whole front end anytime soon. It looks somewhat minor compared to some shit I have seen online. I have worked on a few cars but I expect the RB26 to be my first 'engine out' job at some point.

      Welcome Jan, It's very likely that you are in over your head. You'll just have to learn to swim hard and fast! These old rust buckets have more ways to bankrupt us than almost any other car. But hopefully there's nothing wrong that ruins the whole show! We can help a fair bit. There's plenty here who've been fixing these things for >25 years. cheers

      Hi all. First off, thanks for reading my post. So end of last season I put the car away knowing I was leaking at least two fluids. One of them being rear turbo's oil. I went to my car recently that is waiting in a garage to take a peek with my boroscope to try and see if I can narrow down the souce of oil before taking it out of storage. What I found is not so great I think. The rear turbo is (probably) leaking from the oil drain. The hose and it's clamps are probably the original ones, so most likely just worn out or loose. However I spotted a line of rust going straight down from the turbo oil feed, as if water leaked out of there at some point. Also explains the red liquid that was dripping from my front subframe, which I initially thought was power steering. I can even see coolant drops hanging off the side of the oil pan as well. After a quick hit on the web I found a select few discussions about porous engine blocks. My question is if the pics of the turbo oil feed and the left hand side of the block (imgur link below) looks like it could be exactly that to you. Maybe someone in the community has seen it before and knows what it looks like. If it actually is a porously leaking block, has anyone attempted at fixing it with simple methods like putting a sealer in the cooling system and using something like jb weld on the block surface, or will it just leak in 2 weeks again? I could not find any detailed info or pictures on this topic. If I need a new engine, tell me softly. https://imgur.com/a/knVvmZ8

      Hey all. I'm 23 and from Germany, September last year I bought a mildly modded 1995 GTR Vspec. Looks great and was fun so far, but I already have a list of issues of various severity that I need to take care of, potentially growing longer the closer I look. I just hope I'm not in over my head, I really want to keep the car and work towards it becoming great. I hope y'all will help me out in getting there, I am positive I will need help sooner rather than later to figure out how to proceed. greetings, some pics of the car I posted to imgur. https://imgur.com/a/StKkabz
