    Being a kombidore my kombi runs an ecotec 3800 holden engine and when i fitted it i kept the cast iron exhaust manifolds to keep it simple...but of course they are not suited to a kombi so i ran the pipes in loops around the front of the gearbox which has worked well but i have no access to my CV joints so time to change. Bought a couple of profile cut exhaust flanges off ebay and a lenght of pipe and started fabricating...

    bit hard to see pic in situ but it was just a test fit then take it out finish welding and cleanup and paint. I tried to make the pipes equal length so i,m hoping for added lowdown torque...we'll see! total cost $150!

    What did you do for the collector?

    can be a bugger to seal properly

    when I made my exhaust we were lucky with this score

    Barry for the collector i cut 2 inch pipe and added one inch wedges as you can see then a few tricky little triangles to seal it up...have yet to insert the 02 sensors

    Wow, that brings back bad memories of making extractors to fit small block Chev engines in places they weren't meant to go, like an LC Torana or Windsor motors into an Escorts or Cortina. I think I was 19 or 20yrs old, learnt how to use a mandrel pipe bender and a mig, I'd never seen one before then :lol: The boss had heaps of crap to throw at me for crap welds until I got the hang of the mig, then turned out he didn't have a clue how to use one himself and welded the exhausts using an oxy torch :lol: Once I found out that bit of info, I'd change the settings as soon as I'd finished so he couldn't practice after I'd gone home :p I remember the trick was the weld the pipes together from the outside in as deep as you could get, then weld the hole up in the centre where the pipes all collected together, then fabricated the collector to go over the top, then cut the end of the collector to slide the piece of 2" pipe in (no 50mm pipe back then) and weld that onto the collector .... then hope to hell the pipes hadn't moved making them foul any of the bits the pipes had to work around. One job I was glad to escape from .... pressure from the moment I stepped through the door until I stepped out in the evening.

    How old was the old rubber @tillis? 5 yrs I believe the maximum in NSW.

    Ok I,m over the rush from my new tyres so back to my plywood roof...my son has talked me into keeping it varnished! so had to do some research. The varnish i used weathere and allowed water into the ply in two places which cracked the fiberglass tape i used...so.(boring i know) have repaired those areas with double layers of tape, and read the label of the Bondall int/ext varnish i used and it said for continued use in harsh sunlight use Gold Marine Grade...well it dont get much fiercer than the QLD sun so back to bunnings....

    pretty easy fix really be good if it lasts 5 years instesd of two! but even the whole roof wouldnt be hard to replace...hmmm maybe a pure carbon fibre one next time!
