    Yes, and I thought that I had found the issue. I do believe it improved after adjusting, so I think that it makes sense there could be an issue as you described (that was slightly improved with adjustment.)

    This will be my next step....thanks for the tip.

    Sounds great, I can't wait (ugh!) I see the rocker arm shaft is held by the head bolts, I can't just unbolt it and replace what is needed? (The engine is staying in the car.)

This in turn wipes a cam lobe or two. How did the insides of the engine look? If it looks gunked up that's the oil change issue, if it's remarkably clean then it's the fuel dilution theory.

    If you find a bad cam, since that car is carbureted, I'd bet money that's what happened before they did the carb conversion.
    Check all the rocker arms.
    The engine looked a bit gunked up, but also had been flooded prior to me changing the oil, so I think it was running the 0W0 weight you mentioned (I'm guessing there was ~1 quart of fuel in the oil.) There was no noise when Steve was there, or in the test drive video I have from the week before I bought it. I'm guessing it was flooded and severely diluted the already crappy oil just before I got it.

    I have a bad feeling it's a rocker arm/cam issue.

    Thanks Dave....very much appreciated.

    I contacted Leatherique; they have the OEM grey dye, and a repair kit for fixing cracks.

    I'm also going to re-paint the adjustment bars, any suggestions on a close paint match are very much appreciated.


    Sup Rich!

    Absolutely, my share on exp is to use Krylon's Satin Black (MAXX) rattle can that can be found at Walmart. I sprayed the rails with about 5 coats with 1-2 hours per coat (a full day) on a nice sunny day. Sand them down with 220 grit and if rusted or pitted sand them down with 150 and smooth them back up-to 220 to 320 grit. Coat and recoat. Let them hang freely using metal clothes hangers. Clean with acetone and spray. Take your time with these rails and they will come out great. The rails will end up smooth and nice.



    If you end up redoing/ reupholstering the seats and removing I have a thread on here on how to use my double Zip-Tie technique if in case you can not reuse your original witch-hat tie downs for your seat covers! - bri

    Well, the summer is officially winding down and I've done very little with my car so far (aside from disassembly and compiling parts & tools.)

    The good news is, my non-Delorean related priorities are also winding down so I expect to be dedicated to my restoration work very soon. Unfortunately, most of my free time becomes available during the cold NY winters so I'm planning to get some heat in my small garage this year so I won't be deterred when temps are below freezing.

    I'm looking at this as an option: http://www.northerntool.com/shop/too...FVaRHwodsoMNjw

    Anybody here have any experience with this type of unit? Seems like a good choice for heating a garage.

    So far this weekend things have gone according to plan and I was able to work on my car:

    -Took apart both seats and brought them into my basement where I'll set up on a table in a warm room. I have a Leatherique kit with everything to clean, recondition, fill cracks, and dye.

    -Sprayed various nuts/bolts/studs with penetrating spray. Not much corrosion anywhere, but since I'll be removing the steering shaft, exhaust manifolds & Y-Pipe, I'm going to soak those.

    -Put a wrench on the rearmost driver's side exhaust manifold nut, it actually moved without heat....maybe that's a sign of things to come.

    -Began removing the coolant pipes, I'm going to take the tank out so I can thoroughly address the peeled epoxy mess & re-paint those areas of the frame. So far, the frame looks solid! Just needs to be cleaned & painted....Steve will one day be envious of this car.

    -Finally drained the gas tank, yo! It wasn't as bad as I originally thought; what looked like a layer of thick, black sludge was actually not-so-thick black stuff (floating on water?) in 2-3 inches of gas. That job just got a whole lot easier! It appears that a rinse & wipe will be all that's needed to clean this tank.

    Question: what do I do with 2 gallons of shitty, watery gas?

    Tank removal

    I only worked a few hours each day on my car, but it was a productive weekend: today I removed the gas tank to expose the areas of the frame epoxy damaged by brake fluid. All good news; the gas tank isn't filled with goop, and the frame is solid....just needs cleaning & painting.

    I want to drill holes in my closing plate, anybody here do this & have pics/tips to share?

No big deal to fix but it takes a while. Yes, POR-15 is great for this. I used the grey one; it dries hard as glass! You obviously want to replace the master brake cylinder before you do this.

    I took my tank out recently; I'm happy to report the frame is SOLID, just needs to be cleaned & painted. I'll also be replacing the master cylinder.

    Good pics in my post above.

    Tonite:

    -Removed the passenger side caliper.
    -Removed the master brake cylinder.
    -Removed the brake booster.
    -Began cleaning the closing plate for painting.
    -First round of Leatherique revujenator & cleaner on one of the seats finished, then another round two of rejuvenator (not inmpressed yet.)


    I'm also continuing to spray the exhaust manifold nuts; I'm going to fix the exhaust leak before continuing to diagnose the tapping noise under the passenger side valve cover.
