Damaged SOMETHING with backfiring ...
Well, I finally got my 83 GTI up and running (it needed a new hall sender).
But it seems that the numerous backfires have taken their toll. I actually noticed this new problem just after one of the last backfires so I'm pretty certain it was the cause. The car now makes a pretty loud clanging noise roughly once per revolution (guessing). At first I thought it might be a hole in the exhaust pipes or something, but that's not the case. The car also has much less power. What should I look for here? Thanks and happy 4th!!!! Fred |

Is the engine running smoothly?
maybe a spark plug is not firing or the wires are crossed and not in the proper firing order.

1, 4, 3, 2 is the firing order?
Have you removed the catalytic onverter? I used to go through them about every 50,000 to 80,000 miles. They would rattle and clog up with chunks falling out. I had to remove the muffler once to shake a chunk out of the muffler. Once the car is running well with no skipping, missing or backfiring you can install a new converter. I actualy might have gotten a longer life then mentioned but missfiring will trash a converter. Explosions in the wrong place can cause premature demise.

While I've no experience with this particular engine, I doubt that's the
correct firing order. Every 4 I've ever worked on has been 1-3-4-2. But by all means, look it up rather than relying on Jim's memory or mine. Jim Behning wrote: > 1, 4, 3, 2 is the firing order? > <snip> JRE |

Jim,
WATER-cooled and not AIR-cooled! I see what you are more familar with! ;-) I try to remember when redoing plug wires, but there are times when.......... lol -- later, dave (One out of many daves) "JRE" > wrote in message ... > While I've no experience with this particular engine, I doubt that's the > correct firing order.

Well there are also V-4s in some Saabs and then there are engines that are
1/2 of a V8 engine in some 4 cyl Scouts. That is one strange looking engine since the distributor looks like it could fit its larger V8 brother. Probably more strange engines out there too! It is all good JRE and I think you are correct with the firing order of the VW I4 cyl engines! ;-) Next someone will say that the engines can be inline or transverse. lol later, dave (One out of many daves) "JRE" > wrote in message ... > JRE wrote: >> While I've no experience with this particular engine, I doubt that's the >> correct firing order.

Exciting new data!:
Well, I pulled each plug wire with the engine running, and found that the noise comes from cylinder #2. The noise occurrs with each spark (I checked with a timing gun). Where does this leave me? Sounds expensive. |
