Hi guy's

last week I had a go at changing the timing belt on my 2002 gs300, it doesn't look to bad a job until of course I came up against the mother of all stuck bolts yup crankshaft bolt.

we used no tried a impact wrench electric, Battery and air.

Then the much dreaded breaker bar bumpo starter method which had worked lovely on my 430's crankshaftbolt.

I have even rang lexus to get the service history just in case the timing belt had already been changed and I could just turn my head away and maybe bury it very firmly and deeply in the sand but alas it was not to be. I saw a hack video I am thinking of trying out but reckless as I am I'm concerned how reckless I can be. 

Has anyone tried this method?    Thanks for reading

My old trick for stuck bolts was blow torch - works magic on suspension and exhaust. With engine you would need to be more careful to not melt seal or anything on the area - unless you will change it anyway.

Beside that old good: Give me a lever and a place to stand and I will move the earth  🙂

Hi Krzysztof Yeah I did think about heating it up however I am sure there is a rubber seal in there somewhere I don't think I want to cook and replace. :)

There is a sealant on crankshaft to keep oil inside an engine block 🙂 It should be quite far away from where bolt is as you got pulley between them. Here is example photo form some Lexus engine:

If nothing will work I would try to heat up the bolt. Before heat will propagate from bolt to crankshaft and then seal you got some time as those are quite chunky piece of metal. Seal itself should be fine with a bit of heat as it is keeping hot oil inside plus there is some friction with rotating crankshaft. 

Of course don't go crazy with blow torch. Start slowly and monitor temperature next to the engine. 

Eventually if you are afraid of open flame next to engine especially if space is tight - you don't want to start fire from any oil leak - you can use heat gun. Those can reach 500C plus temp too.
