If you put the #1 pistion up top dead center and the timing marks are aline you will be able to adjust the distribuator in line with your #1 pistion to get you goen.............Adjust the distribuator to give max power to the vech while in drive and holding the break with acceleration with safety in mind..........Mhen max power is felt at its best then use timing lighe to fine tune........Hope this helps.

I have a oz xe 4.1 lt 250 xflow motor which i have rebuilt and put flat top pistons in bored out 60 thou shaved yella terra head 15 thou and has a very mild cam after lining up timing marks the inlet


when setting up the valve timing it is always done on the exhaust stoke.. Place the piston on TDC and set the valve timing so that the exhaust valve is just closing and the inlet is just opening. Rocking the crank a bit before tdc to a bit after tdc will produce a movement where the exhaust starts to close as the inlet starts to open. This is known as valve rock or valve overlap. The cam modification is of no consequence as the as all that is modified is the valve duration , not when they open or close. With the cam now timed to the crank turn the crank 180 degrees and set the ignition timing to the degrees advanced recommended ( 10-12 degrees bftdc is recommended for starting). Place the HT leads in the correct firing order and when running use a timing light to adjust ignition timing. If you are fitting a new cam then you must bedding in grease and when the motor starts it has to be run at around 2.000rpms for around 10 minutes to set (harden) the cam lobes or else they will wear off very quickly.

Diagram for engine timing for a 3100 Chevy V6


It's on TDC so align marks on cam shaft and crank shaft with center of cam & crank shafts and the ECM will go from there. so you will have to change the timing chain if its loose or worn out.

Have rebuilt motor new everything from mazda now i have pooo12 code retarded intake cam checked timing with sst and ex and in cam are in perfect alignment with sst the solniod tested out fine . the only...


remember 1 thing..dont confuse cam timing with ignition timing also if the belt or chain has alignment dots or marks on it ..it can be put on backwards and still line up marks correctly but but in a different position making the cam timming off i have done it and seen it done before like an old chevy when you put timming gear set on you line up the 2 dots alot of people think that is tdc and they set up ignition and go to start it and get pops and bangs well thats because the the install dots are actully 180 degrees out from tdc so you remove the distributor and turn it 180 deg. and now she starts right up i think you have 1 of these cams a tooth off or your using marks incorectly or belt or chain is backwards making dots align in different postion appearing correct

Will a broken timing belt damage the valves in 1990 toyota camry v6 dx


No damage will occur. This is a non-interference engine so all you will have to do is make sure the timing marks on the cams and crank are set properly.

How do i set the timing in my 95 sonoma with an older carberated 350 from start without taking timing cover off?


There are two kinds of timing, cam timing, and ignition timing. You don't adjust cam timing, it is set when the timing chain is installed. The timing chain cover is supposed to have a pointer welded to it with marks that line up with a mark on the harmonic balancer. (depending on the year of you engine these marks veri in appearance. Ignition timing is set while the engine is running with a strobe light that is triggered by the number one spark plug. On this engine (if it's stock) around 8-10 degrees BTDC. The ignition timing advances with cetrifical weights inside the distributor as well as a vacuum diaphragm. If either of these fail you will have a performance issue with a lack of power, and acceleration. If you are concerned about the cam gear being worn out yes they do wear out. Chevy made the gear teeth on the cam gear out of nylon to make then quieter, the replacement gears are usually cast iron. If you are thinking about changing the timing gears, the crank gear has to be pulled off with a puller, a lot of guys don't bother since it doesn't wear like the cam gear.

I need to know how to fix a timing chain on a 1990 v6 3.1 chevy cavalier and do the valves get messed up when it breaks?


remove everything in your way to get to the cam timing housing cover in front of the block. Set #1 cylinder to dead top center. install new chain or belt...put it back together and litely loosen the ditributor to adjust for timing...once timing is set hold ditributor and tighten bolt. Shut down and recheck timing with the light.
