OK well after trying to swap 91 cams into my 95 and dropping a washer and fishing it out and having my car down for a couple of days. I've encountered a new problem. I thought i had the timing set up correctly but when i tried to crank it wouldnt start, so i break it down and try to turn the crank by hand to set the cams to tdc. But i can only turn the crank about halfwya before it stops. Now i understand its hard to turn the crank by hand but this is really stuck, Is it possible i misaligned the cams and the valve is hitting a piston? Im not sure what to do. Everyones timings problems are centered around tdc but i cant get to tdc because of the crank,

Any help?

Im dying here guys...

If it's stuck, even if you used say a wrench, then yep, your valves are nailing the piston. You probably didn't set it right. The KA24DE has 2 sets of chains as you know. This is gonna be fun so hold on to your belts. If you took the sprockets off completely without noting their position, you may have to align the whole system. If the valves are indeed hitting the piston and you cranked it as in you tried to start it up with the key, then the damage may already been done.

What you have to do now is take off the front cover of the engine on the head and take off the oil pump... yes that's right the oil pump.

You have to set the bottom chain, two shinny links have to match up with the crankshaft sprocket and the idler sprocket. Put the oil pump back on then set the top dual chains so that the shinny links match up with the cam sprockets.

If your tried to start it and now you cant even crank it by hand you might as well take the head off and get some new valves. But try what silvia007 said you might get really lucky, good luck.
