valve timing

[podunk]

I recently changed the top timing gear and chain and tentioner and tentioning rail, while in the process my son pionted out to me that I let the chain skip one tooth or maby two we are not sure.
So with the crank @ tdc on #1 how do you tell if the valve timing is correct as there are no marks on the chain and none on the gear.

the car is 300 sd 5 cyl turbo diesel

year/class/ engine code ,would be helpfull,

[podunk]

1982 300 SD Inline 5 cyl turbo diesel S class I have been told that from 1981 thru 1995 the turbo diesel engines in all of these 300 SD (s) are all identical.

great data !!, your the MAN !!!. thank you thank you
I would have never found the marks without that picture, it sure runs fine, im still working on the cold start problem got any tips for that ?

if you have power to the heater plugs(if fitted) i would remove them them and test individually,hows your fuse box?is it showing signs of corrosion-check all fuses for burnt/fragile ends/check on bulkhead next to battery for fuses(can be well hidden) and a right pain to get at.should go some way to heal the beast!

ya, got new glo plugs that seem to meter correctly, and new battery, maby the old gal just dont have all the compression it should have

[mechy1barry]

may be a lazy starter motor?

[podunk]

spins good , new battery !!!

[mechy1barry]

if only from cold it hard to start,perhaps fuel filter and/or lines are allowing fuel to drain back when left standing(hows the filter?)timer relay for glow plugs may have to short a duration,

[podunk]

the car has sat for about 90 days , but just 2 weeks pryor to that when the "cold start" problem began, I changed all of the fuel filters and glo plugs and did the timer test on the glo sys. All checked out good, thats when i replaced the timing chain, top gear, tensioning rail, tensioner, & front seal. the car runs better now than ever has < !! i mean WOW second gear rubber , but still hard to start up on that first start of the day no matter what time am or pm and it is hot here in Texas right now.

will have a word with our merc tech tomorrow,see what he comes up with.

[podunk]

cool

[mechy1barry]

the man he say-glow plugs,remove and test each one,make sure all glow nicely-fuel draining back over night due to loose pipes/filter o ring faulty.sorry to repeat myself and put doubt on your hard work,but these must be 101% .glow plugs must power up for max 10 secs through ign,compression test on cylinders should be 24.0 to 30.0bar,have you checked valve clearances?
