Fuel in coolant bottle, injector cups??

[oceanstateperf]

So I found diesel spraying out of the cap on my coolant degas bottle and have learned that this is most likely a sign of one or more cracked injector cups. I've been told that the engine has to come out to make the repair ............ assuming that you replace all 8 while you're at it...........because the rear 2 on each side are under the cowl and can't be accessed to use a slide hammer for cup removal. I've seen some info on using the 1 1/4" tap to cut some threads and then a slide hammer with adapter for cup removal.

My question is has anyone here tried to pull the cups out with a threaded puller of some kind without removing the engine and then is there enough room to drive the new cups in correctly given that you'd be fighting for working room with the cowl over hanging the rear of the engine? Maybe just as easy to remove the engine and take the opportunity to clean up the engine bay, check the oil pan for rust, etc but figured I'd ask for anyone that has "been there and done that".

Thanks, Pat

Ya, I should be able to do it with the heads on by using the 1 1/4 tap trick but I've been told that the whole engine will have to come out to get the rear two cups out on each head because of the cowl overhang and lack of working room back there.

Thanks, Pat
