Jason tackles his turbo
Good friend of this site Jason gets to grips with his 8v. Looking in the garage behind, he shouldn't struggle! Here's Jason...
And with that, I reached out to the guys at integralingham, they had mentioned they had just done a turbo swap on their evo, so while using that as an occasional reference, I cranked up my plug in heater, turned up the classic rock and began the 8v turbo teardown. In the words of the Immortal Jeremy Clarkson, how hard could it be?
Turns out, not that hard.
Day 1: Took the front blinkers lenses off ( two screws each) and removed the bulbs for safe keeping, the front grill (three screws on the top) the hood (two bolts per side, 4 total) and then the front bumper (two bolts). For one, in the future if you’re ever doing an oil change, coolant flush, whatever, PLEASE do yourself the favor, spend 30 min and take all this stuff off! If I knew it was this easy I would have done this as I spent most of the summer crouching in the engine bay trying to reach the lower radiator hose twisting into angles that no fully grown adult should have to endure unless you were a gymnast. Total time: 30 minutes tops.
So far so easy.
Day 2: Wasn’t as easy as day one but still wasn’t impossible either, but there were some differences between the evo spec car and my 8v so I feel the need to highlight them here.
First thing I did was loosen all the fittings for the Air Conditioning hardlines. This proved difficult as they most likely haven’t moved in nearly 30 years, and after punching myself in the face once while trying to muscle off one of the threaded collars, I busted out the wd40 and let it do the heavy lifting. Fortunately the lines had no refrigerant in it ***If yours does, it would be best to dispose of it properly…however you see fit***. Once I removed the lines, I was able to pull off the lines for the oil cooler. Of course some dripped out, but I had a bucket nearby . I then unplugged the electric fans, pulled the lower radiator hose and let the coolant drain out. Then I removed the intercooler , airbox and the associated piping to free up some of the room. Then I took the oil cooler, radiator and fans up and out (they are set in and just require a gentle tug out) Once again, I want to harp on the fact that I am not a professional mechanic by trade, but if you take your time to remove things and see where they bolt up, it’s easy to do.
Somewhere in the process, I had removed the plastic air diverter shroud. Once it gets in the way, that’s how you know its time for it to go! (That and I honestly forgot where in the process I removed it..) total time was roughly 5 hours
Day 3: things got interesting, not difficult but sometimes a bit of a head scratcher. I removed all the associated hoses from the turbo (which most of them snapped like twigs as they lost all remaining properties of “rubber”) I had the manifold bolts to remove along with the oil drain and feed lines. One of the major differences is that the EVO utilizes a tubular manifold whereas the 8v uses a traditional “log” type manifold. Another is that the oil feed for the turbo is bolted to the 8v manifold, so off that bolt went along with the downpipe bolts.
A little heaving and tugging, (of course I missed one turbo support bracket…and that’s why it wasn’t moving), one bump on the bumper support which nearly knocked me out and somehow drew blood at the same time, and out the turbo and manifold came!
Fortunately, it appears that the turbo has minimal shaftplay, and the blades appear to be in perfect shape, but as the turbo is damn near 30 years old at this point (and at 52000 miles, where the Lancia manual suggests a turbo rebuild at 60k miles) its dirty, but in decent shape. I plan to send the oem Garret Airworks T03 turbo to Kirk at Boostlab in Florida (theboostlab.com) for a rebuild as they rebuild every turbo under the sun and have a stellar reputation in the supra community (my other fun car). Once that arrives back, that should fix the oil burning /blow through issue as shown in the video and then I shall be putting everything back in…but there are lists of things I plan to do while I’m in there.
Cap, Rotor, Lines and plugs
Air Conditioning condenser
And a few other things I just can’t remember right now.
Overall, I just want to stress the following statement: THIS CAR IS NOT COMPLICATED and the previous walkthough was a HUGE help . Take your time, look around, and learn your car. If you can turn a wrench and know the basic workings of a car, you are qualified to do this job; don’t be intimidated.
We're very grateful to Jason for sharing his work with us, his 8v is unusual in having air con fitted, this made his task more difficult. This is a great little Delta, and rare in the US, Jason will have it running sweetly for the Springtime.
Jason later told me a friend of his called in to the garage, this friend pointed out
the oil dripping from the back of the dizzy. Hmmm! So the pool of oil on the
garage floor wasn't all the turbo's fault!
Jason's turbo will be fitted back soon, with lovely new pipes and fittings, we look forward to your update Jason.
I was looking for a winter project for the long
North Eastern US winter, and since I had recently
revamped my other project car, the only thing left to do
was to see what could be done for my Lancia.
I didn't think it needed much until I noticed this...(see video)
Finally got a chance to put everything backtogether
and it runs like a dream. Idle is spot on at around 8-900
when warm, boost is nice and pulls consistently to redline,
and more importantly NO OIL DRIPS ON THE GARAGE FLOOR
NOR NO OIL COMING OUT OF THE EXHAUST.
For bonus points, my car had a keyfob on it that looked to be an aftermarket addon from japan back in the early 90s. It worked for about 5 months then suddenly stopped without reason. While I was reattaching everything and regrounding alot of the wiring (because I was in there, and why the heck not) I must have fixed the right one because now central lock works on my keyfob! It was a surprising little gift after I slaved over this car for all of those months.
After everything was said and done, it was a challenging yet rewarding learning process of knowing the ins and outs of the car. It came to a point (as I was tuning the wastegate) that I was so familiar with all of the bolts that I didnt need to label them anymore and thus just threw them into a pile; more importantly I was able to take the car from running with fluids, torn down to adjust the wastegate, and back up and running for testing in ~3 hours...which although a pain, was definitely an accomplishment in itself as I think I went from beginner to advanced in "Delta mechanics" skill level.
