Re: Before I touch anything! - Engine gurus

Ya... Fair enough


Well, I think tonight I'll pull the head off, and see what's going on.

Before, when I first started it, it would knock real hard, and then stop, so, I'm assuming there's more to this issue..

Re: Before I touch anything! - Engine gurus

Ever have that deep feeling of regret, and knowing, '' I shouldn't have even touched the fcuking thing'' feeling?

I has that now..

But, probably a good idea I did take it out, before something went horribly wrong.

Its simple you're just over thinking it.

retime it and take you're time. Make sure all the marks are aligned and you're good.

Out of curiosity, do you think it's possible I can't turn it when It's all bolted down, because it's in gear?

I'm at work, or I'd try..

I feel like I'd know if there was a bent valve, is the thing. You may be right, just over thinking it. It worked just fine before, and I haven't touched anything. Should be fine.. Friend came over last night, and said the same.

The valve clearances are way out to lunch, so that could have been the knocking noise.

Oh ive had that feeling to often. When I was 13 I decided id rebuild the too end in my 250. I reused a 25 cent cir clip instead of getting new ones. That clip cost me almost 2k in the long run. Destroyed my engine

Put it in neutral, pull the plugs out, and take the valve cover and ignition cover off.

It should spin easy. if it doesn't your timing is prly off.

Re: Before I touch anything! - Engine gurus

even if you DO take the head off, if you can't set the timing on the 2 cams properly, you're fu ck ed.. just later than sooner this time. and yes, if it's in gear and you turn the motor over at the crank with the 12mm socket, the rear wheel will just spin. If it's not turning over something is wrong. you need a manual. cap bolts for the cams need torqued down in sequence. And i suggest not pulling the head off just yet.. if you do, get a new head gasket before hand and those head bolts FOR SURE need torqued down properly.

Thank you everyone for your help!

Really appreciate it!

Turns out... I'm an idiot..

Took it out of gear, and spins perfect now! Timing is set dead on, and all is well!!

Happier then a pig in shit.
