I was driving on the free way and my car just dies on me. I pulled over and tryed to start it again but it just cranks. Also while the engine is cranking the cam gears and timing belt are not moving. Did I jump a tooth or is my timing belt ****ed

beecee18

is the timing belt still present ( wraped around the gears or?)

Sounds like the timing belt broke. You may not see that it's torn, but if you take the bottom timing belt cover off(the one behind the crank pulley) you should be able to see the belt is ripped completely in half.. Not a good thing. If you have an interference engine, you most likely bent some valves. Try taking the timing covers off and inspect the belt. Don't crank the engine over anymore.

Keep in mind the crank is what spins, so if it's ripped, the crank will spin, but the cam gears will not.

MurtazaDSM

yes belt is around gears still im going to start taking it apart tomorrow

MurtazaDSM

I just replacled the timing belt car has less than 200miles

MurtazaDSM

I found the problem I guess my belt jumped but how? Andy why did my valve cover gasket melt by the cam gears

beecee18

probably occured from setting the timing belt wrong, or setting the T-belt tension inproperly

use service manual instruction to reset the belt properly and then try to start, hopefully the valves didnt smiley face your slugs.

for a second there, i thought seized cam for sure. but that would normally occur with the exhaust cam rather than intake, since it gets hotter.
it did get hot though. no doubt about that. i'm thinking it still may have seized. usually a lack of oil pressure is the cause. possibly an obstruction to the cam journal passages. and that definitely will cause the belt to skip.
since it is a b vtec motor, it's gonna be tight tolerances. highly likely bent valves

but i'm interested to know though, you said the starter was cranking, but cam gears and crank weren't moving. not seeing that as being possible, or extremely unlikely, as the crank is driven by the flywheel when the starter meshes. so if the starter is cranking, the crank must be moving...unless the crank has cracked. but i doubt that.
so what happened when you tried to turn it over? was the starter cranking? was the crank moving? were the cams moving? there are holes in your story that need filling

beecee18

yeah your right about the heat on those oil rails,
ive never seen a b-series with charred oil on the top-end like that,
maybe remove the cams and check the cam journals and caps for garring.

If you decide to do that I would still check for cam to camcap clearance with platigauge to still make sure your within spec.

And your right again, as with most tech threads, about holes in the story

GL OP let us know what comes of it.

I have seen this before. turned out the oil filter had collapsed and reduced the oil flow to the head. the cam siezed in the head and the key way for he timing gear on the crank sheared off.

If your cam did sieze you will need a new head and cam's.

el crapitan

^^now that makes sense. sheared keyway.
you can tear it apart and mic everything, but i'd be prepared to consider the motor to be unsalvageable.

could have also been a plugged pick up. guess he'll find out with the teardown

beecee18

OMFG

this is what I mean by voodo wierd ****!

If this is the case OP your MOMO is for the birds!

MurtazaDSM

I think your right my brother was suppose to do a oil change while I was at work, turns out he changed the oil but not the filter now my crank is smooth no grooves for the crank pulley and belt if ****ed up

MurtazaDSM

so I need a new head and crank? or can I just reuse my head and get new cams my cams are done for

el crapitan

you starved the engine of oil. it will need to be torn apart, cylinders checked, rings checked, cam and crank bores checked, crank, cam, and absolutely, all bearings checked. it's gonna be a full teardown if you want any guarantees.
pull that crank gear off. have a look at that key way

beecee18

If the keyway is still present and crank and cams still spin, maybe the timing belt just simply failed???
Keep us posted as you tear down OP

Solster

Pull the cam caps and the cams off and take Pix i'll bet the heads Chewed to **** and the cams Are fried.

if this is the case you will just need a New head and cams but i would Take the time and rebiuld the lower end as well. might be cheaper to just get another Engine if your not up for a FULL rebuild.

Ether way i Want your Timing covers

Solster

Never mind the Pix was Very dark on my end but after i lightend it up i can see the melted aluminium around the cam on the #1 cam cap on the Exhaust cam.

el crapitan

if the head was starved, the crank will have been too. especially since it was the intake cam that seized. she is done

MurtazaDSM

just gunna swap in a ls for right now and rebuild the whole thing

MurtazaDSM

since my head is done for what should I look for in the block to indicate damage besides scorched cylinder walls and piston play

Solster

scoring on the crank and rods

if your going for a NA rebuild or Near stock rebiuld.

i would get the block decked, crank polished, cyl honed, New rings, new rod and main bearings, NEW oil pump.

Also i still would like your Timing covers
