Strange engine 'knock' problem

Featured Replies

Just today as I was going around a freeway on-ramp 'cloverleaf', I accelerated at the top to merge and the engine started knocking or pinging like crazy, and sent a huge smoke cloud out the back. I let off the gas and then accelerated again, and the pinging and smoke were gone. What could have caused this? I only use at least 90 octane gas, so i'm sure its not bad gas, and the fact it only happened after I went around a hard right turn.

Check out this thread. It's all there. I haven't bothered to do the PCV mod (yet), and don't know if I'll ever bother. It only effects me on hard uphill freeway merging situations, and I just take it slow and stay in the breakdown lane with my hazard flasher on. I think most motorists take one look at my old jalopy and assume that it's on its last legs.:)

Hey...that thread link isnt quite right there...

Hey just noticed you are in the same area as me :) I live in Burnsville. Some of us are getting together this SAT for a Subaru pow-wow. We could fix your PCV system right there. I prolly got all the parts laying around my garage to do it. Basicly just need a new plastic T fitting and some more 5/8" vacume hose.

Thank you WJM. This problem has been discussed before and the poster can search "odd white smoke" or "hard right smoke" etc to find more info.

 

For the Loyale fix, See edit in my post above.
