Any suggestkions greatly appreciated.   1997 2.5 dohc engine.  Replacing head gaskets.  Removed bolts to all 4 cam sprockets and 3 sprockets came off easily, but the right intake will not come off, even after flooding bolt hole with penetrant several times and letting sit all night.

 

Suggestions please.   Am hoping to get camshafts and heads off today.

 

Thanks!

GENTLY use two lg screwdrivers and CAREFULLY work it back and forth.

I had the same issue, I ended up tapping it gently with a rubber mallet and it popped off.

Thanks for suggestions   just got it off but damaged it a bit during process and will replace it    but learned as went along  i had tried the rubber mallet but that did not work for me,,,   engine is in car so tough to get two big screw drivers in but can get behind sprocket on its right side as face it and pull screw driver handle towards you and give a gentle pry out  and then turn sprocket the other way as far as it will easily go and then a gently pry out on that side and keep going back and forth repeating the process     i learned at end if screw bolt on till it almost touches the sprocket and then look from side as turn the sprocket, that if distance between the sprocket and the bolt head varies as turn the sprocket then that shows one side of the sprocket has come off more than other side so then work the side that has not come off as far    little at a time and back and forth and sprocket eventually came off  if ever have to do it again i think will be able to get it off without damaging the sprocke,,,,   will put anti sieze on all 4 when put it back together,,, thanks again for suggestions - is greatly appreciated!
