My 84 1.6 - Help wont start

[CRSMP5]

wheel with tapered lug seat yes.... streach head bolt on flat washer and surface... i do not think so...

loosing that bolt last.. not a great idea.. but id remove the other 9.. then beat the headbolt socket in.. and if it strips.. then id try next best fitting torx, or allen.. or hell wrap xzn socket with aluminum foil to "tighten" it up in the hole... but if all other 9 bolts out i think the last bolt will have least amount of torisonal force on it..

...or weld a hex driver to the bolt head, or drill it off as proposed before....

or sell the car as-is to one of us.

fixed the image, still looks terrible.  looked ok on my phone lol.  Anyway the 12mm wont even fit in so I think if i hammer it in I might be ok. 

Once off the car, whats the best steps for "giving it a bath" to get all the crap off of it so i can bring it in the house (hopefully the gf doesnt notice) and in to my office where i have a nice desk to work on it.

[Jetmugg]

Plenty of cleaning solvent, a parts brush, and a power washer (not necessarily in that order).

[atherton213]

ok ive got all that ... hopefully it will be off today and i can get it cleaned and update all of you waiting for whats up with the car

How snug does the 12mm fit in the other headbolts?  Is this the original engine?

[atherton213]

Fits like it should in the others

seems to work on any bolt that is stuck,  each bounce, it wants to ride back up the ramp of the threads a hair, as well as jostling any  bond that has formed.

I just know it has worked for me. If you don't get it out there is usually not much left holding it.

Get some lapping compound on the bit for purchase.

i cant get a single head bolt off.... Cant remove them by hand or with an electric impact gun (harbor freight had a sale today)

seems like they were torqued by a Sasquatch

I use a 3' breaker bar personally...

I hate to jump a thread; especially after only skimming info, but,,
it sounds like you haven't loosened any head bolts yet, if you have you may have ruined head. it may have warped. once you loosen 1 bolt the others must come out (loose) quickly. this can be a problem also if you drill out a bolt.


I personally use a 3' breaker bar too and get a length of pipe if needed(especially helps since im not getting any younger). the problem with this stripping the bolts, a snap-on socket helps and good leverage, make sure the socket is properly seated in bolt too.
f*** the harbor freight things, and you'll need a better impact to do this, air may do the job, I don't think an electric has the power. if you have an air impact don't turn the air all the way up so you blow something or ruin the air gun.
if you use a breaker bar and with or without a pipe make sure you have good leverage, don't slip and bust yourself. it usually takes a lot to get these bolts loose(and tight), but it sounds like the people who worked on this before didn't know what they were doing; the bolts sound too tight to me.

i vote next size torx and a nice hammer and a big ass pipe on your breaker bar.

[RustyCaddy]

May be try air before the breaker bar if at all possible.

While 11mm head bolts can twist off at the top of the block using a 3 foot cheater the 12mm do seem much stronger.
