So my daily driver is now dead on number 3

Engine : Bone stock 1.8 liter w/ L-jet (1974)

2 days ago I am driving as usuall, pushing it pretty hard 4k rpm for about an hour in 5th gear, i notice a loss of power, number three is dead. I pull the plug wire while running and no difference.

so

I park it overnight and do a valve adjustment in the morning. Number 3 is still dead. I pull the plug and look at it. It is black as hell and not shiny or oily. dull black. I pop in a new plug. still dead. I switch the injector leads from front to back. still #3. I swap injectors from the same side. still #3

this means no compression right? I (IMG:style_emoticons/default/blink.gif) just did the adjustment the night before and it was .006 on intake and exhaust. How can the adjustment be perfect and the cylinder be dead.??? (IMG:style_emoticons/default/confused24.gif)

last note: on the dead cylinder, if i pull the injector lead from that one, the rpm drop fatally as if it were only running on 2. but as i said it makes no difference if the plug wire is on or not.

What gives??

i guess the motor is comming out again, but what am i looking for (IMG:style_emoticons/default/icon8.gif)

Compression test. But you know what it is gong to say. Leakdown test will show you where it is leaking (head, valves or rings).
Is it rattling or knocking?

Of course I think you should stop effort into your doomed 1.8 and build the 2056.

Was the #3 exhaust valve adjuster further out than the rest? Thats usually a pretty good give away of a burned/sunken valve. Ask me how i know..

Have you checked that your number 3 spark plug is firing by grounding out the body of the plug while cranking the motor?

How is the distributor cap?
How is the rotor?
How are the grounds for the injectors?
Are you getting fuel at that injector?
Sounds like it may be less complicated????

engine is knocking.

plug is new, wire gives a good arc when touched to ground.

compression tester is lost in garage. (will find)

when i did the valve adjustment on that cylinder it was a bit tight but nothing out of the ordinary. It was really close




thanks for the imput

How does the starter sound? If you really do have a dead hole, the starter won't make noise when that piston is at TDC. So the starter will go "RR-RR-RR-..-RR-RR-RR-.." That's when I figured out about my last dropped valve seat.

Having had my hands on and in that 1.8 of your, I echo the sentiment I told you years ago. Build that damn 2056 already and stop pissing away time and money on that tired 1.8 grenade.

Let me tell you Joe,

First you should not be enjoying the "Raging Bitch" while adjusting your valves. You could get some dirt in your bottle, or, you could totaly #$%# up on that paticular valve. Heck you could make both of the valves on #3 too tight.

(IMG:style_emoticons/default/chair.gif)

Second, you should try the Captains method using a felt tip marker and doing the entire adjustment without even taking the distributor cap off.

(IMG:style_emoticons/default/smilie_pokal.gif)

Thanks Capt it now runs like a champ. I was ripping up the pavement on my way in to work this morning. (IMG:style_emoticons/default/driving.gif) I even passed a boxter going "slightly faster" then he was. (IMG:style_emoticons/default/laugh.gif)


Its turning into a pretty good day

(IMG:style_emoticons/default/idea.gif) Do you guys think its possible to adjust the valves on that one cilinder without jacking the car. It is paralel parked but i got about 2-3 feet in front and back, i am pretty sure i could squeez my head in front of the tire pop the cover and tweak the valve. assuming i am about to drop the seat, i would much rather go out with a bang than a put put put...
