Hi have a f22b3 1995exi was wondering if any one nows the specs on the tappet gaps .Also can u adjust them and advance the motor ?? Wanna put it in a motor carna


the valve timing on a motor is set and cannot be altered. The length of time that the valves are held open is determined by the lift of the cam and this period of time that the valves are held open determines how much mixture is allowed into the cylinder. If you advance the cam shaft you may gain extra mixture and a bit more power but on a single cam the exhaust valve timing is altered and so the advantage of the advance is lost. If you want more go from the motor get specially ground cam shafts ( hot cams) As to tappet clearance, if you have hydraulic lifters then they self adjust and thee is no clearance measurement. If you can adjust the tappets then most engines run .010" hot inlet and .012" exhaust hot Setting the tappets closer means that they open sooner but they also close sooner so the amount of mixture is reduced as the time for the mixture to enter the cylinder is reduced.

At times it is as if my car has no power,very heavy on fuel and lifters are noisy. Isuzu 3.2 V6 24 valve 1999 model


The cam profiles are different between in and exhaust cams so switching them may be the start of you problems. The noisy lifters probably came from the incorrect cam not allowing them to adjust properly . The rest of you problems probably come from the fact that the CPU is having trouble analysing and adjusting .

you need to look into your specs of your vehicle.. look to see if your car is a non interference motor if it isent most likely you bent a valve. if it is then u might just be binding up with your valve and piston do not try and put a bunch of presure on it!!!!! u need to raise your cams then move crankshaft.. let me know what happins.....

I would like to know the intake and exhaust specs to adjust a solid roller set up on a 383 stroke with 202 heads.


You need to contact the cam manufacturer to get those numbers. If you need to get it fired up you could set the intakes at .016 and exhausts at .018 to begin with but without knowing what cam, that's only a ball park number. Numbers also depend on if you are running iron or aluminum heads as the expansion rates are different. After setting the lash, rotate the engine by hand and check the valve springs for any sign of binding. Also check to make sure the push rods have adequate clearance and aren't rubbing on the through holes in the heads.

Replaced head gasget and since that the tappets have being noisy set them to what it said could you help thanks


http://www.izook.com/shoptips/valves/valves.htm

Here is the procedure.
They give hot and cold specs.
The hot specs are much larger, and you might have set them when too cold to use the hot specs.

Or you many not have set the crankshaft to TDC and done the right set of valves.
But being overhead cam, you should have easily recognized whether or not the cam was free from pressing on the tappet.

I also do not recommend light oil like 5w-20. I prefer 10w-40 or 20w-50 unless you live in a very cold climate.

RENAULT CLIO 8 VALVE TIMING BELT SNAPPED WHERE DO I FIND THE TIMING MARKS? HOW DO I SET THE TIMING UP . IS THERE A DIAGRAM ANYWHERE ? WILL IT BEND THE VALVES ? THANKS


hallo
first let me know year, engine code (or at least typ of engine 1.2, 1.4...). and I will send you picture for timing belt.
and it will (did) bend valves, so you`ll have to remove cilinder head *** well.

1998 4cyl.camry had a stuck valae due to bad gas{varnish}. removed valve cover, got valve unstuck. had to remove exhaust cam, but not the intake cam. need to reinstall and time exhaust cam. can not...


simple to figure that out . the key ways are always up on camshafts. it allows for them not to fall out when assembling the engine . so use the balancer to determine tdc (top dead center on cyl one) and make sure both keys are straight up . (just loosen the cam retainer nuts and look to see what set of marks they line up with and dont forget t re-torque them to factory specs somewhere between 22 and 28 ft lbs but not a lot more) , google the specs up to be sure
