Dun Blowed Up… NASA AIX Javelin update

blown motor? check…

Ok, the motors blown but the question was, how bad? I took off the valve covers and manually rotated the engine. none of the valves moved and the engine wouldn’t turn a full 360*. It hangs up on something. I decided instead of seeing if it’s “just” bent valves or “just” a broken timing chain that I wanted to pull the whole motor and take it to a machine shop. Don suggested Rob’s Automotive Machine in Hayward. So, I went to Jeff’s on Saturday to borrow his hoist. Spent the rest of the weekend tearing apart a car that I spent a year and a half building… fun. anyway, on Tuesday morning I did the final pull and put the engine in the truck and took it to Rob’s.

Rob sr. disassembled the motor and here’s the report:

1. ALL valves bent
2. Timing chain AND gear broken
3. Timing cover is broken
4. Crank is cracked
5. Cam mounted distributor gear is kinda chewed up (all the teeth are knife edged)

The last issue that was uncovered is that the bearings are all pretty burnt up. If you’ve been following the blog you’ve probably read a few times where I’ve seen my oil pressure light come on and had to get off the track quick. I’m guessing the burnt bearings are due to that. I’m going to install a dipstick this time and USE it…

So, it’s not looking too good for me making the Willow Springs race… Next race is in June back at Buttonwillow. I’m considering missing that one too because it’s only a week after the Chumpcar race. I want to get the rebuilt motor in AND get the car lowered before I try to run it again…

Here’s some pics.

    Hello,
    Sorry to hear of your engine troubles.
    Did your engine builder do the oil line reroute mod to help eliminate oil distribution problems?
    Also does your class allow for extensions and bracing on the front spoiler like done on the 71 Trans AM Javelins?

    Really enjoyed your videos. Great Job!
    Like being in the car.

    Thanks
    Dave

  2. Hi Dave,
    yes, the engine has the lifter valley oil line modification and yes I can add extensions to the front spoiler like the trans-am cars. I actually tried this at the last race. check the previous post and you’ll see a picture. couldn’t tell if it was helping or hurting though so I took it off… I’ll try again once the car has been lowered and the grill area closed up.

    Sad day, indeed. I’d seen the last post and was hoping for better luck. I supposed it could’ve been much worse, but that certainly is a kick where it hurts. Sorry to hear! Sounds like the oiling issue really needs some attention. Any thoughts on running a drysump? Not sure that its legal in AI, but I thought I saw AIX allows it. I’ve been considering it on my build and after seeing your problems, I may give it some more thought. The initial costs may be well worth the insurance.
    Good luck getting the motor back together. I’m going to miss the updates and video. I’m finally getting my track car project off to the shop this coming friday to get the cage put in. The blue Jav is running (with a couple if bugs to sort out still), so I can finally turn some attention to my other project. Obviously, your blog (and Scott’s posts) have been a great resource for me going into the build…I’ll owe you guys a beer, at least!
