June 13, 201312 yr Hey i just got finished reinstalling the cam tower to replace a dropped follower for the cyl 3 and resealing the oil pump. i have tripple checked the belr timing and i seem to still be running on two cylinders. I checked spark, even swapped wires to check that they werent reversed. i'm at a bit of a loss.the roll pins are incthe cams so they shouldnt be installed by someone else wrong. but still I can ground out either wire and get no rpm drop. drivers side is fine though. ill be re-pulling the cam cover tonight to see if i have dropped lifters again. but i know they were properly inplace when i put it on. HELP! I NEED THIS CAR ON THE ROAD YESTERDAY. My job and therefore my childrens home is riding on it. thanks in advance
June 13, 201312 yr Author Ill also add i gave not yet adjusted dizzy or tps. but if one side is running good and the other isnt.....
June 13, 201312 yr Did you rotate the crank 360 between installing the belts? The cam marks should be 180 from eachother, and should point diagonally up n out, and down and out Pass/drivers side respectively when the crank is at TDC compression. It would also be helpful to know what excact model....I'm assuming EA82, but is it MPFI or SPFI?
June 13, 201312 yr Author Spfi. And from what i saw you line it up with the three lll marks not 0 which would be tdc. Yeah i did rotate 360 between. Cams are 180 out feom each other
June 13, 201312 yr Author Also the video showed the timing being straight up (like the notch in the cover). This is the video i followed http://www.google.com/url?sa=t&source=web&cd=1&ved=0CDcQtwIwAA&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DZG1p70E4VXc&ei=-Q-6UZHwBeitiAK1sYGAAg&usg=AFQjCNFafBFYK35eSrxhIm7G5xGW58uGeg

Cams are 180 out feom each other Yes....3 marks = one cam staight up, one straight down. these are the belt installation marks. 0TDC= dots diagonally up/out and down/out for disty installation at #1 cyl this is the Disty install proceedure, or a good double check to see if the disty is 180 out. Firing order is 1324 cyls arrangment looking at engine from front of car. 3 4 1 2
June 13, 201312 yr Author Being spi/tbi it cant be fuel Being as drivers side bank are fine it cant really be ignition timing. All i can think of as other issues is valve timing (that should be right), or lifters which the oil pump reseal should have helped. If you can think of anything let me know. Ill be pulling the valve cover tonight (late tonight due to family stuff) to check those folowers.

June 13, 201312 yr Author you're on. Do you want my paypal now or after i snap the pics tonight? With crank pointer at center of those 3 marks one cam is pointed dead up the other is straight down. Checked it twice last night before starting. Once after and once this morning. Each time i spun it 360 to make sure they reversed and kept pointing where they were supposed to

Each time i spun it 360 to make sure they reversed and kept pointing where they were supposed to Now turnt he engine over until the dots are diagonally OUT from eachother, and the crank is at 0TDC. Then pull the disty cap and see if it's pointed at #1. Verify valve timing by doing a compression check if needed.
June 13, 201312 yr Author Only compression tester i have is a rubber tipped versio where you push it to the hold. Ill hive ir a shot if itll fit in there though.
June 13, 201312 yr IF the cam followers have fallen off, there are other likely causes other than oil pump pressure/flow. There is some amount of technique involved in reassembly (usually involving a thick grease); did you verify that all of the followers were in place before putting on the cover? You could also have collapsed/bad hydraulic lash adjusters, a plugged oil gallery passage, bad cam-tower/head sealing ring, excessive venting at the tower oil-relief valve (not its proper name).
June 13, 201312 yr Author Resealed that side after using tje grease technique to replace the fallen lifter i found after buying the car. I can only guess they have fallen again. Ill know tonight for sure. Anyone done the lifters while head is on car before?
June 14, 201312 yr Replacing the fallen follower* Hi , you need to check if the valves are stuck in an open position on the ones that the rockers have dropped off. i had a motor that sat for a long time, upon starting it , some rockers dropped like you found , the valves were stuck which created the open space for them to drop off. after using a soft hammer to thump them several times the valves seemed to begin to seat and when i put it back together the rockers did stay in place.
June 14, 201312 yr Doing the HLAs in situ shouldn't be too tough... unless they are stuck in their bores, which might require some ingenious "persuading". I assume that you had the the cam case off to do the rockers the first time, right? The HLAs are just a slip-fit in their bores.
June 14, 201312 yr Author Just got home. to late to do any work (niece's birthday party ) their just slip in? Awesome. I'll likely have it apart again tomorrow then
June 14, 201312 yr Yes, they are just slip in... but I have had a few that refused to slip back out with merely kind words.
June 15, 201312 yr Author Photo's and problem. The follower dropped again. Looks like I need a source for lifters cheap. Sorry pics took so long. I had family problems that couldn't be avoided. Edited June 15, 201312 yr by CarpeNoctem
