HELP my timing belt shredded!

[kt239]

I am waiting for aaa at the moment because my timing belt got tore up on my way home. I wanted to get the communities input as to how screwed I am so here's what happened. I was cruising at 65 on rt376 and I herd what sounded like road debris under my vehicle. The motor shut down and I pulled to side of the road to see what was the problem and saw my timing belt town up half way. I heard no clunking or obvious signs of valve hitting piston. I want to put my spare oem timing belt on when I get home but here's my question... If my timing marks are all good and lined up there should be no issues correct? As dumb a question it may be I just want to be sure.

Well finally got the other front cover/oil pump on and spun the motor around. It moves freely with little resistance but I'm teetering with calling bent vales on the play. I will finish reassembling the motor and do a compression test within a day or two here!

Bent valves? Yes, yes indeed. I been busy the past few days so this got held off but after pulling the head I was presented with a magical site.

As you can see cylinder 4 got it the worst as all 4 got popped. Cylinder 1 got two and cylinder 2 and 3 don't have and noticeable damage but all 16 are getting replaced with new valves. I will check the guides when I get the proper compressor to remove the locks because apparently neither one of the two I have fit . On the plus side all parts are here (even guides if needed) and there no piston damage besides little graze marks. Also checked the rod and main bearings and they checked out fine. Gotta love this motor for its simplicity and the fact it's a pretty easy motor to work on as a whole.

Also if you are going to replace all the valves, Get the Engnbldr Stainless steel valves, also he has the bronze guides for a good price.

Well made the c clamp spring compressor with the socket ant that worked like a charm. All the guides are crack free and look good so got lucky there. Next step is lapping compound and reassembly! Thanks for all the guides BogusSVO they were very helpful.
