Loose dipstick tube

My 2zz track car has a loose dipstick tube. The o-ring wasn't in the best shape which I replaced and pushed back into the hole in the engine block however I'm assuming it's lost a bolt(s) which holds it in place. I can spot the bracket but there's no way I can access to put a new bolt in without dropping the engine.

Does anyone know if it's just the bolt holding the upper part of the tube or whether there's also a bolt where it inserts the engine block (like my BMW Z4 which I also had to replace the dipstick o-ring on recently) ?

There's two retaining brackets on the guide tube, the one on the top where it also holds the O2 sensor connection and head cover.
Then one around halfway along the length that goes to the block.

Not sure how much help it'll be, if any but the photo shows the mounting bracket beside the thermostat housing.
You might be able to reach up to it from underneath, I know you can see the thermostat housing from under the car.You cannot view this attachment.

Thank you : )

I think the 2ZZ one is slightly different and I think it's just the upper retaining bolt. Will give it a go this weekend, trackday on monday!

It was my understanding that part of the job of inserting a 2ZZ into a roadster, is to swap the dipstick tube for a 1ZZ one....??

That's incorrect. The 1ZZ needs to be bent and the oil reading is inaccurate (I own another 2ZZ MR2 with this approach) whereas the 2ZZ tube is clear.

Thanks for that.
