![]() Components wear like chain stretch or point replacement might need a tweek, but mostly engine timing stays put. Unless someone messes with it, ignition timing will not change over time enough to matter much. Therefore whatever you changed the timing to now, is also wrong or at best unknown. Something in the way you measured is wrong. The initial or crank ignition timing isn't/wasn't 45 degrees BTDC, no way no how. Not trying to pick on you but this has a way of making things worse and worse as we go along, if our premise is wrong. ![]() Here's an example where making assumptions can get us into trouble. I set her at 11° and the whole engine would shake and rock.OK. I've read these 390's live to be around 10-12°. I checked the timing and it was way over 30°. connected it's ten times worse.įor some reason I can't find the correlation between my timing and the vacuum advance. unplugged it will run fine until it wants to use the V.A. Once I plug the vacuum advance back up the whole engine shakes and misfires. The engine loves 10° without the vacuum advance. Once I take off and get above 40mph she starts to hiccup and backfire (especially on a hill I have to drop to 30mph and baby it all the way up). I unplugged the vacuum advance and the engine sounds beautiful all through the rpm range (while in neutral). I set her at 11° and the whole engine would shake and rock. It got to the point where I couldn't stop or she'd die on me without staying in the throttle. I decided to put in new point, rotor, dist cap, plugs, and wires. Initially the engine was running a little rough. For your next timing cover replacement or repair, shop O'Reilly Auto Parts for complete timing cover gasket sets and timing cover assemblies to help you complete your repair.I've come to this site numerous times and received all answers to my questions of the years. Any time the timing cover is removed for service, it is also important to replace all of your timing cover gaskets and seals to ensure a lasting repair. It's also important to check the timing cover itself for any damage, as timing covers are often made from aluminum or plastic and even minor cracks can contribute to oil loss. However, a worn out gasket is not the only reason oil might be leaking near your timing cover. This can result in oil leaks, coolant leaks, engine overheating, and other issues. Over time, your timing cover gaskets may crack or fail due to age or other damage. Timing cover gaskets and seals are typically made of rubber, cork, or silicone, and are designed to withstand the high temperatures and pressures generated by the engine as it runs. These seals keep the timing chain or belt free from debris and help prevent oil from leaking or becoming contaminated. Many timing cover gasket sets also include a press-fit seal that fits around the crankshaft and seals the opening that receives the harmonic balancer.
