Rusty manifold bolts..what do you think of these?
Discussion
Hi,
Just toying with new 200 cel headers/stainless manifolds.
I've read quite a few stories re bolts snapping so had a look to check the condition of mine. I have no frame of reference so wondered what others thought of these re how far gone they are..To my mind they look ok and would think with plenty of WD40 they should be Ok to have a crack at but I'm quite aware many before me have thought the same and ended up regretting ever starting the job...
Any thoughts on these bolts by comparison?

PB blaster ordered. Next stop a swear jar and plasters...
What the concensus on heat? I've not got oxy/acet but would a blow lamp be any use? I assume the thinking is the expansion and contraction helps to break anything seized and you need to let things cools as I presume whilst still hot its expanded and could be harder to remove?

Keep us updated OP..What the concensus on heat? I've not got oxy/acet but would a blow lamp be any use? I assume the thinking is the expansion and contraction helps to break anything seized and you need to let things cools as I presume whilst still hot its expanded and could be harder to remove?
Ha..Will do. If you never hear from me again....

You'll probably get a few that snap but take it as easy as you can. I found most of mine would crack off OK but would go tight and snap and it really didn't take much force. I'd apply some heat and work them back and fore as much as possible and use wd40 once they are moving. Fingers crossed the ones that do snap are in the middle with good access.
Nothing puts more dread in my mind than having to remove an exhaust manifold that looks like that...... You just KNOW its going to be an utter ballache, involving swearing, rust in your eyes, more swearing, a drill or 2, couple of trips to buy helicoil kits and more drill bits.
And it still usually ends up at a workshop anyway......

Yep thanks for the comments all. Headers ordered.
Have to admit I have that very strange feeling that's not often talked about......The feeling of setting off/embarking on something when you know it's almost certainly going to go wrong......Quite strange and it does beg an obvious question..
Not sure I've got much option though as I figure whoever goes to take them off will likely have similar luck so to add salt to the wound I'd actually be paying for the privilege! Granted they would no doubt resolve the situation more quickly, ( and comfortably! ), as they will be more skilled and better equipped but I could imagine a pretty hefty bill for labour..
My gut instinct is to go for it and hope that I don't snap too many. I'll try shocking them and use heat and PB working as slowly as I possibly can. Depending on the result it may end up at a workshop if it looks like going properly pear shaped but time looks to be on our side currently so worth a try...
The other option is to not bother but I hope it'll be worth it in the end...
