Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
Hi Im Dave, the alignment tool should only fit one way. get the cams turned to where the tool slides into the slots.
if they are upside down, the tool wont fit correctly. it'll look like it might but it'll be just a hair off
that is correct. exhaust notch at 5ish and intake at 7ish.
well anytime you do timing work, you ALWAYS manually turn the crank once the chain/belt is installed to make sure there is no interference. if they were 180 out then the car would probably just not start.
no. you didnt bend the valves. believe me you would have heard it
those sprockets are vvt, they wont stop ... you have to line them up with the timing marks and keep them there. there is a tool for that too.
they spring back to the rest position. if they arent spring loaded then just turn them back to the rest position and you should be good
dont worry about the other tool i mentioned
they have to align with the marks. did you have the sprockets off?
see if this helps you
meaning it wont start?
are you sure your on the compression stroke at tdc at the crank?
that doesnt mean you on the compression stroke. put a piece of thin paper/tissue over the spark plug hole while manually moving the crank. when the paper blows up or away, you're on the compression stroke then take it to the top
redo it. it needs to be dead on
you sure you got the gauge on tight? coz that aint even close brother. you need to be reading 140-180
remove all tools from anywhere and do a regular compression test. hold key to start for 5 cylcles for each cylinder
ok. when you initially started the job, did you initially finish and try starting the vehicle without making certain everything was lined up?
ok. being 180 degrees out will cause low compression also. turn the cam notches up then, but ive never seen it or have done it that way.................give it a shot
dont be so worried about bent valves, as long as you manually turned the crank before starting it every time.
ok. go here and you should find everything you need........http://workshop-manuals.com/
ok man. ill dig up some pics
i believe i told you 5ish and 7ish on the cams.... here is the zero setting
ok. do compression test agian this time pour a tablespoon of motor oil down the spark plug hole then connect the gauge. see what the compression does
ok. sounds good
have you attempted anything more?
let me look back over our notes..........
that tool should not fit either way. but the position of the #1 cylinder cam lobes will be the key.
per the pic
correct on the int and exh valves. the tool should fit easier one way than the other..... odd....it usually is almost impossible to fit the other way
just make sure the cam lobes on cylinder 1 are kind of pointing at each other. may 10 and 2 o clock lobe position
let me look that up
Use camshaft adjustment tool:
Install camshaft adjustment tool(###) ###-####Camshaft Adjustment Tool See: Tools and Equipment/999 5452 Camshaft Adjustment Tool at the rearof the camshafts.
little more info on that cam tool. First screw in the part of the tool intended for the exhaust camshaft (drilled hole)
Then carefully turn the exhaust camshaft clockwise with the camshaft adjustment tool until the intake camshaft tool can be applied (threaded hole)
Install the intake camshaft adjustment tool
First pass ............................................................ 20 Nm Second pass ........................................................... 60 Nm Final pass ...................................................... Tighten 130°
looks pretty good, id like to see the one on right face the left a bit more, but if thats zero. that zero
well hows it going?
you can hold the cam with a wrench there should be a pace for a wrench on the cam somewhere
looks good to me bubba
rotate it manually just to make sure everything comes back to marks
you're good my friend
what!!! that compression is horrible!!! anything under 120 is horrible........holy hell.
does it sound like it wants to start?
you getting fuel? spark?
ok, but im worried about those compression readings. are you holding the gas pedal to the floor while doing it? and letting it cycle at least 5 times?
checking in to see how its going?
thats really not good news if the compression came up enough to start the car. that means the pistons rings are shot.
what did the compression come up to when you added oil?
piston rings are shot
well it ran good enough before on the low compression because it was timed correctly. i think since it looked 1/2 off on one cam and the compression is low, thats what the issue is.
normally on a healthy engine a 1/2 tooth doesnt matter.
just start from scratch
getting ridiculous aint it?
the vvt's only need to match up with the colored links. the only mark you need to worry about is the crank
hows it going?
ok bud, how about accepting the answer and leaving a 5 star rating. ill keep thid open sfter you rate me. no problem ....thanks
