1987 Celica 3SFE Cam pulley
Okay need a bit more help...
I cannot get the cam pulley bolt to budge...
I Got a 14mm socket on it & a wrench on the cam hex to prevent the cam turning and the socket has rotated on the nut twice. I'm worried I will round off the bolt. I might be able to remove the camshafts without removing the pulley but I can't see the knock pin to position the lifters properly. Any tips or tricks appreciated!

Thanks

RE: 1987 Celica 3SFE Cam pulley
Not sure why you'd want to remove the cam sprocket (oil seal?) but those bolts are going to be on TIGHT so you must use a snug fitting socket, not a 12 point and not one that's worn. Personally I'd be using a breaker bar with a black "impact socket" because they are rather sturdy. I also have a 14 inch adjustable wrench that I use on the cam because it's nice and wide on the jaws plus long for leverage.

BTW, do not use heat on that bolt. Both the cam and the sprocket are hardened so heat will ruin things.

Thanks Rupe! Especially about the heat...I was considering that - thinking I would only destroy the oil seal.
My manual has removing the pulley as a first step before cam removal. Also the #3 timing cover plate is between the head and the cam pulley. I've got a blown head gasket so I am removing the head to send out for machining. Can't get to the head bolts w/o removing the cams. I might be able to pull the intake cam with the pulley attached by disconnecting the #3 timing cover but I can't see the knock pin to position the cam lobes correctly for removal

Not sure what this "knock pin" is that you speak of but I can't think of any special issues where cam gear position would be a problem for bolt removal unless the valves hit the pistons. If that's the case just rotate the crank enough to get the pistons down a bit then worry about it on reassembly.

It's on the camshaft end bearing. The camshaft removal is sequential so the lifters push the cams straight up when you remove the final caps.

RE: 1987 Celica 3SFE Cam pulley
Ok, now I see your dilemma. They are looking for equal upward thrust so the cam doesn't cock and screw up a bearing on the way out.

On that note, you are back to getting a decent grip on the sprocket bolt. It may pay to spend a couple of bucks and purchase exactly what you need. Good tools last a lifetime, and some of mine are older than me.

RE: 1987 Celica 3SFE Cam pulley
So bought the breaker bar, worked like a charm. Got the pulley off and positioned the cams per the manual, removed the journals as specified and the cam is not pushing straight out. Reset the journals adjusted the cams again and tried a second time. Cam is still cocked. WTF? manual says to remove 1,2 & 4 then 3 with knock pin @ 10-45 deg. Left of TDC. This puts lobes on #4 straight down & I assume only #3 should be compressed...

RE: 1987 Celica 3SFE Cam pulley
Yeah, WTF indeed! I thought maybe they were onto something with all that fancy footwork but you are back to square one.

Personally, I have always taken cam cap bolts out slowly and just paid attention to anything that looked like it might jam up. I worked for Nissan for a LONG time and they always advised against removing the cam first, although in your case you said it keeps you from a clear shot at the head bolts. Of course this was in the old days when everything used solid lifters. IOW, I could use the factory tool (or improvise) to pull out the rockers (cam followers) first, then there was no tension on the cam itself. Is this possible in your case? I really don't have a good answer other than paying attention to whatever lobe is still under tension and removing those bolts last... and evenly... to reduce cocking the cam.

RE: 1987 Celica 3SFE Cam pulley
Found another manual which had same knock pin position but hint that 2 and 4 lifters were to be compressed, I'll give that a go...always something! LOL
