What have you done to your DeLorean today?

Here are a couple of pics of the spark plugs that came out of cylinders 1,2,3 (#3 is the one closest to the new plug sitting there).

What vintage are "Autolite" plugs if you had to guess? I don't think this is what Dunmurry used, and they haven't been changed on my watch (October 2007 onwards).

Hard to say. Autolite has been around for about 1000 years and is still in business.

Is that sand on the thread tops?



Photos for new insurance value & a Christmas drive in the rain....... Loving it!

Not trying to be a pain, but not wanting to make a mistake either... what did you mean by "loosen the A.S. housing?" I might be mixing up acronyms, sorry. And loosening by way of nuts and bolts just physically holding it to the engine I hope, and not much more? Got a part number I can reference for what to loosen? thx.

EDIT: I replaced the spark plugs on the RH side so far, cylinders 1,2,3. The tips of them didn't look terrible, but the threads were pretty black/dark. The top end too for the electrical connection was not very clean and shiny either. I expect this will help a lot overall with how well the car performs come Spring.

Air Sensor housing. You really need to change everything now that you ripped the plugs out and disturbed 34 year old wires. If you don't your engine bay may light up like a "Grucci" fireworks display come nightfall!
If you really are afraid of the fuel fittings then just remove the;

1) Idle air regulator and the brass pipe that slides into the A.S. Hsg.
2) Vacuum solenoid at the back of the hsg. retained by a 6 MM Allen bolt
3) Two 6 MM Allen bolts holding the A.S. Hsg. support braces to the intake manifold runners and wedge a small socket under each brace.
4) Now you have access to replace the dist. cap, rotor and all wires as well as the plugs.

Never do half a tuneup. It's self defeating! You'll be happier in the end with the full job done with no need to go back there soon.

Yes Autolight has been around and is as well known as AC Delco. With all that grit on the plugs some is sure to find it's way into the cylinders. The trick is to blow out the plug wells with compressed air BEFORE removal or....lacking that grab a vacuum cleaner and have ago at it. I suggest doing back to Bosch "Silber" or Copper spark plugs. Stay away from Bosch Platinum's as they have a tendency to fail in my experience.

And what would be the consequences of some grit falling into the cylinders if I might ask?

Probably nothing but it could damage a valve or the seat. Particles of sand & grit can be rather hard on machined surfaces.

I've done my plugs but gave up on the dizzy cap and leads as it seemed very involved and was still running ok, but would like to re-visit it.
Is there a photo/video guide to doing this?

Today I finished installing the rear fascia.

Fascia installed yesterday..

LED exterior kit from DMC..

Testing the bulbs on my OEM circuit boards. I had to tighten the rivets and sand the contacts with 1000 grit.

My license plate bezel was really faded, so I couldn't leave it raw. I painted it with SEM trim black...

The finished product...

Now I can move to the interior.

Looks good. I'm thinking about doing this in the near future. How do you like those LEDs?
