Wedge Posted April 2, 2011 Share Posted April 2, 2011 Hi everyone I was in the process of installing my new Pat1 made oil pan and when i removed the stock RB26 pan I cought these little bastards near the in and around the oil pick up the biggest chunk was on the edge of the block. They must've fallen form inside the pan because after checking the bottom of the pan carefully I found some more tiny pieces of metal. The engine had an almost perfect compression across the block before removal form the skyline it came from. Im getting paranoid now I dont know what to do, should I open it and check the cylinder walls or something else. I didnt pay attention when i drain the pan the first time to check if their was metal bits in it. I cought a piece of black silicone sealant in the big banjo bolt on the block the one that feed water to the 2 turbos. Pictures of the metal parts. What are they from ? Thank you for the advice Quote Link to comment Share on other sites More sharing options...
Wedge Posted April 2, 2011 Author Share Posted April 2, 2011 Oh and BTW the engine was said to have had a rebuild when it was in japan before the previoous owner bought the car Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted April 2, 2011 Share Posted April 2, 2011 That looks like turbo parts .Maybe it blew a turbo since the pan has been off, and was left in there...?? Just a guess. Quote Link to comment Share on other sites More sharing options...
Wedge Posted April 2, 2011 Author Share Posted April 2, 2011 Yes it had a blown turbo I changed it since but the PO didnt know it was busted because (and this is what he told me could lies to)he bought the car from Japanese auction had it delivered decided he want to keep the body and part the rest and this where i come in he mentioned he just drove it from the ports custom in BC canada to his home and once around the block to film it driving around because i asked him to film rolling around. I had the compression test on film to it was in the 160 and over all across the block. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted April 2, 2011 Share Posted April 2, 2011 looks like the part on the left is from a beer can. haha but on a more serious note i would check the snails too. Quote Link to comment Share on other sites More sharing options...
Wedge Posted April 2, 2011 Author Share Posted April 2, 2011 Beer tap was for size chart lol .Both my turbos have been checked one was all good the other one I had to replace it. Im more scared of the fact that I cant find the other half of the ring. pictures of the dead turbo looked like it sucked a rag left in a IC pipe Quote Link to comment Share on other sites More sharing options...
ZT-R Posted April 2, 2011 Share Posted April 2, 2011 (edited) haha i know that... couldnt be a wrist pin could it? i doubt it would use a snap ring that looked like that... did this thing run? well i take that back wrist pins dont have oil galley like that i dont think.

kiwi303 Posted April 3, 2011 Share Posted April 3, 2011 The half ring with holes in it looks like a turbo journal bearing sleeve to me. Quote Link to comment Share on other sites More sharing options...
Wedge Posted April 3, 2011 Author Share Posted April 3, 2011 The N1 turbo i had on it had all their bearings and they have more holes in them. And ZT-R yes the engine was supose to be working i have a video of it . If the PO said the truth that is. Quote Link to comment Share on other sites More sharing options...
pat1 Posted April 3, 2011 Share Posted April 3, 2011 Yep that's turbo journal bearing parts. I guess it could be possible that the turbo could take a crap and the bearing parts could be washed out of the turbo by the oil in to the pan. No big deal. I would inspect the bottom end a little. I would put money on it that the clip and other bearing parts are still in the turbo. If your that worried about it pull the head and inspect the cylinder walls but if the walls were messed up the compression would be off.

RB26powered74zcar Posted April 3, 2011 Share Posted April 3, 2011 I'd do one heck of a oil galley etc. flush, and pray you don't ruin the next pair of turbos... Quote Link to comment Share on other sites More sharing options...
Wedge Posted April 3, 2011 Author Share Posted April 3, 2011 (edited) RB26powered74zcar how would one do an oil galley flush ? Im wondering why their is sleave bearing parts in my pan since i have BB turbos on it. I thinking maybe the rebuild it supposedly had in japan was from that blown turbo but not cleaning the mess in the pan and im asking myself can i trust them to have done the rest of the job well. I think ill pull the oil pump this afternoon to check for wear and metal parts. Edited April 3, 2011 by Wedge Quote Link to comment Share on other sites More sharing options...
pat1 Posted April 3, 2011 Share Posted April 3, 2011 For any of the material to get past the pickup screen and the oil pump and then the oil filter to oil galleys is slim to none. Inspect the oil pump and go from there. Quote Link to comment Share on other sites More sharing options...

kiwi303 Posted April 4, 2011 Share Posted April 4, 2011 Im wondering why their is sleave bearing parts in my pan since i have BB turbos on it. Did you put the BBs on yourself? Or are these the turbos that came with the motor? Maybe the PO blew his turbo and just slapped another turbo on without doing any further work.

jakeoster Posted April 4, 2011 Share Posted April 4, 2011 (edited) That just looks scary. How did that get through the intercooler? Or did it get in through the turbo's oil return line? I must have been very fortunate. When I first got my 280z going with the RB25 I got a little gung-ho with the Greddy boost controller. The first run trying to tune it, I had misread the directions and hit over 18psi on the stock turbo that was already gushing oil into the intercooler charge pipe =x Edited April 4, 2011 by jakeoster Quote Link to comment Share on other sites More sharing options...
ZT-R Posted April 4, 2011 Share Posted April 4, 2011 that would have had to go though the oil return. Quote Link to comment Share on other sites More sharing options...

Maybe the PO blew his turbo and just slapped another turbo on without doing any further work. The BB turbos were on when i got the engin and like the picture above had one destroyed that was a BB to. My guess is the first set of turbos this RB26 had the oem ones probably blew. My oil Pump is all clean BTW i checked yesterday. Quote Link to comment Share on other sites More sharing options...

I would do a quick look at the crank case but I doubt your going to find anything else. Have you turned the motor upside-down? Quote Link to comment Share on other sites More sharing options...
Wedge Posted April 5, 2011 Author Share Posted April 5, 2011 Ya i did when I removed the RB pan to install the amazing one you made me. I checked all the pistons from the bottom and i couldnt find anything else. Quote Link to comment Share on other sites More sharing options...
