My Mach 1 is F**ked up!! UPDATED with more Pics

[greenbullitt]

holly crap! thats a lot of freaking bolts holding those mains in!

some have 2 less per main...but yes, it is lol

[JC316]

to clarify...99+ Teksids did NOT use these (and have a 9mm cross-bolt)

Ah, ok, I haven't dealt with the 99+ teksid, just the older teksid.

If you pull the chains make sure its at tdc and hold the cams with vise grips and let the chains loose on one side. Then relieve tension on cams. I have seen people skip this and knock the heads off of all the exhaust valves. Good luck

The motor is locked guys, I can't turn it to TDC! Also I don't think it actually matters since EVERYTHING is coming apart anyway.

Greenbullit & JC316: thanks alot guys I had no clue it had those extra bolts!

[greenbullitt]

you're welcome

[jw33]

then pull out an air chisel, smoke wrench, or BMFH and go to town...

[majorownage]

those pieces are from the cam caps....

looks like the cam(s) seized to the journals, heated, and/or snapped the ladders and generally FUBARed it.

GL with the rebuild. BTW you might want to start looking for new heads

[majorownage]

4v mod-motor = probably not a great platform to learn about engine assembly

4v is super easy...what are you talking about? No BS in setting the valve lash, pushrod geometry, etc. Just slap it together and make sure the chains are on correctly.

I'd just buy a built shortblock or longblock and be done.

Might even be a good time for a termi swap.

If you local guys are like here you will be better off financially to order from MMR or the likes. If it isn't a common pushrod they charge out the ass here.

Can you tell where it's locked up at?

When mine threw a rod, it got a chunk of rod stuck down in between the block and one of the counter-weights on the crank and locked that bitch up on the highway LOL

Once I pulled the motor out, I turned the crank backwards and freed up all the junk and was able to get the motor to turn around so I could get it to TDC before I pulled the heads off

seized cam journals

yea...you might as well just throw the entire engine in the trash...unless its an 8 bolt crank

Not sure I know what you mean here? More detail please!

I've looked at all the cam caps... Everything is intact! ???

Also why would I need new heads??

No I can't tell where it's locked up at. What's the importance of getting it to TDC if EVERYTHING is coming apart??

[Wish4svts]

It is an 8 bolt crank... Why would I throw it in the trash just because seized cam journals???

well.. those pieces are for the ladder bars that hold the cam caps together

you cannot find cam caps and just install them, you would have to get them align bored into position. And good luck finding someone willing to sell cam caps...that junks the head they were installed on

[majorownage]

I know for a fact those are pieces from the ladder bars.

taking off the heads is super easy. just take the impact wrench and take of the primary gears on the exhaust, you do not need to align the crank a certain way because you KNOW its fine right now. Otherwise the valves would already be bent

AND take a picture of the top of your heads
