My 1974 2.0 had a 5800 limiter in it. Handy at the Autocross for those stretches that the gears aren’t quite tall enough to reach. Just bounce the rev limiter a couple of times then dive into the corner.
I’ve been using these on various cars for more than 20 years and never had a problem until last week. The car was running fine but I picked up a tach bounce at cruise so I assumed it must be time for a tune up. Pulled the cap and found out that the part of the rotor that contained the rev limiter cracked and let the bits from the limiter escape into the distributor. The ground strap scrapped a bunch of material off of the inside of the cap and sent powder all over the inside of the distributor. No harm done. Just had to pull the distributor, clean it out and put a new rotor in there.   |
