My carbed 1.7 has a tap tap tap/knock knock knock noise at idle. It seems to disappear with engine speed but I can't tell if it's just the exhaust noise covering it up. I adjusted the valves using the Capn's procedure and set them all at 1 full turn past contact, engine has hydraulic lifters. Still the same knock/tap noise....
What is it? Is it fatal? This engine has been good to me and I just need it to last a little while longer until I get myself a FI engine hopefully soon... |

I'm going through the same can of worms. Convinced I hear a knock... pin pointed it to the passenger side valve cover.. (I believe it is the forward valve). Mechanic thinks I'm hearing exhaust leaks. He redid the copper washers and copper nuts (I didn't have copper nuts). There definitely was an exhaust leak... but the leak is seperate from the knocking noise.
Still knocking... some people say it's normal valve noise, some say drive it until it blows chunks. I wish I could fix it though. To me it seems like one valve does not hold it's adjusment- you set it, then it get's sloppy. |
