    TD5 Manifold stud bolts fixed :)

    Well lastnight finally got the beast back on the road was off so long as got mucked around by a engineer who said he was there and was not when i took my manifold in,so then had to get it taken elseware. did nto take him long or cost much to get it machined. then dad got the grinder out and got rid of the webbing on the manifold for me put some flame proof header paint on it. turns out my oil leak was from the warped manifold, the oil that goes through there was blowing out and going everywhere. plus there was 2 bolts, one on the turbo and one just behind (found that after) that were super lose, and had been dropping oil for ages. so they are now tightened up too.
    had to move the air con compressor out of the way to get to the broken stud up that end of the block. two of the broken ones came out easy as. that one though, the easy outs were blunt, my drill bits had given up, and then that one just did not want to cooperate! had to re tap the hole with a bolt. LOL!
    but is now all fixed, and no spots of oil underneath and i have a power increase!!! hopefully fuel consumption has improved as well. seems to be purring all very nicely

    Looks very spiffy with the new paint. A constipated job well done Dont you just love engineering workshops? They always seem to be shut or busy or sleeping or or when you want them!!! HeHe
    Cheers Scott

    thanks haha yeah! oh yes! this particular one id heard good stuff about, but cannot say my experience was a good one. he told me he was there so i could drop it off any time. so i did the extra drive, and then he wasnt there. so screwed myself up for no reason! he could have said yep, but ive got errands to run between here and here. not to worry though, the other place did a great job. and all done now i think it is not leaking oil but i am not 100% need to clean all the sump off today to monitor for sure. theres a little hose that goes to the turbo that was culprit along with the blowing manifold for the oil leak. im not sure i trust the little hose or its bolts haha

    I did this on my old TD5.

    I can also recommend drilling the outside holes out to 10mm. Leave the inside holes the regular size to ensure alignment with the ports. Having a little room around the outside holes means the manifold can move a little rather than shear off the studs as the differing metals expand at different rates.

    Cheers

    oh yours looks good!!! and nice new turbo, how do you find that? i am looking to get a new turbo in the near future. just trying to sus out the right one that will boost power but not give me a lot of lag. cant remember what i put on my skyline but that came on fast which was great. the manifold looks good black, i wanted to paint mine black, but they had no black heat proof paint in
    the only thing i did not do was drill those end holes bigger, but hopefully it wont break any studs again. my oil return line was leaking. may or may not need to replace it!

    I believe the turbo was designed for a 3.0 Nissan Patrol. It's a variable geometry turbo so no waste gate and very little lag. It spooled up quick but still worked well at higher engine rpm.

    I got it through turbo engineering in Thomastown Vic. It was a few years back now so not sure if they are still in business.

    Cheers
