From the book Points 0.45-0.55mm (0.018-0.022in) Dwell 49-55 degrees Idle speed 700 +- 50 m/t or 750 +- 50 a/t timing (no vac) @ idle 2 +- 2 degrees BTDC timing with vac reconnected @ idle 9 +- 5 degrees
e15 engine has different setting for timing depending on location for which car manufactured.Some of those as ,low as TDC and as high as 19 BTDC. Cam timing for e13 Cam keyway pointing DOWN, Mark directly opposite keyway aligned with mark on belt cover. Hope that helps.

Well there ya go. If! i can read then the book and me agree. 18 thou points.10 ta 12 degrees RUNNING at idle-vacuum connected.[Oh and that camshaft is 16 degrees out. WRONG TIMING MARK .NO FAT CHICKS.] supernova and crazy horse. ya worked out why that subaru wouldn't go

cam keyway pointing down! what would you consider the keyway! as in referal to the previous pic " http://i213.photobucket.com/albums/cc119/TurboZBuzz/Engine/Eng2008-03-15_07.jpg " ths is exactly how my pully was set when i was putting the cambelt on, though, once i had set the cambelt in place i let the bearing spring do all the work while i turned it over slowly a few times to make sure the timing points hadnt strayed from the original setting, I then felt the tention of the belt, felt that it was tight enough, then assembled, a day later the cambelt was making noise from being over tight, so i had my uncle ( retired diesel mech) come have a gander , he loosened the belt to how he felt the belt should be, and then its been assembled and running without noise since, I only checked the timing after i left my car with a mate for a few days and the car was still pinging, and you all pretty much know know were the car is with this.

In other words cam timing oposite to that in snoops picture.As for needing a DTI a lot of that comes down to experience and having the right "feel"After years of experience you should be able to detect the changeover from up to down on the probe.Sure if blueprinting an engine use a DTI but lets be honest this is just a bog standard e13 nissan motor.Anyway to change the belt you have to remove the crankpully and there are timing marks on the lower housing and crank gear.When reassembling you should notice if the timing marks on crank pully line up - if not you should check the problem then.Really is a combination, belt gear marks, rocking cams, tdc, rotor position and on it goes.

I'd say the subaru wont go cause its got the cams mixed up.I admit I know nothing about subarus - well thats not quite right.I do know I never want one or to ever work on one.

Stupid 4 cam subaru's think they are soo smart dont they!

my uncle ( retired diesel mech) come have a gander , Well if he knows what acamshaft lobe centerline is and how to check valve timing **on the rock** then ya might find that there will be approx. 12 to 16 degrees diferrence between the 2 marks-Even though they appear to be 180 degress opposing-as one is on a **high point-tooth** and the other is on a **low point hollow*** Oh and ANY.OLD SCHOOL. ROCKER.lobe centerline/degree wheel engine tuner/camshaft timer. Who KNOWS
It is exhaust closing. inlet opening
wil see that when subaru change teir exhaust ports from ends of the cyl head.to both in the CENTRE. Ya can say the timing marks are right. but ya'll NEVER get the engine to run.
snoopy221,

This was an older single cam subaru. pushrod engine. there are 2 camshafts for them due to the inlet and exhaust valves being physicaly swapeed in the cyl heads. nd yep he juss went by the timing marks.

As for belt tension.My rule of thumb is to let the auto tensioner do its thing after making sure no slack on drag side of belt.Once again a feel thing but usually you can get a 90 degree twist on the longest run just with finger pressure if all is well.Another trick is to turn the motor by the crank bolt a couple of times, then unlock tensioner and turn motor backwards about one tooth by the cam bolt.Then relock the tensioner.

The arrow is not opposite the dot.
ginga4lyfe,
Oct 3, 9:18pm
what picture are you looking at! because the one dot is directly opposite the arrow on the outer of the pully ( the arrow is pointing down!)
ginga4lyfe,
Oct 3, 9:20pm
I had let the auto tentioner do its own thing, but somehow that was too tight, ill reset the tentioner and do the one tooth ccw trick, lock it into place spin it over a full revolution then make sure the tention is right with the 90deg trick
crzyhrse,
Oct 3, 9:20pm
No. The arrow points to the root of the tooth on the timing pulley. the dot is on the crown of a tooth on the timing pulley. There are 40 teeth so they cannot be 180º apart.
ginga4lyfe,
Oct 3, 9:25pm
splitting hairs much! there are two dots, one next to the little "2" on the pully and a dot opposite to the arrow , it doesnt have to be exactly 180 degrees apart to be in relation to "opposite" of something

mumble f**k.[counting teeth crzyhrse! shit ya keen-LOL] ginga that cam is 16 degrees advanced and THAT is why ya dizzy AIN'T in the centre of it's bolt holes. NOTE. those that CAN do. Those that can NOT read the instructions. Sheesh ginga it's ONLY a 1200. juss caus they call it a 13. points at .018 thou timing at 10 ta 12 degrees-and No Fat Chicks.K. [Oh and good luck with the **Duplex**-now lemme see is duplex another name for a phrophylactic(condom)-mmkay. yip double check that ***duplex** timing chain in ya E13.LMAO] -Note to intrade-it's got a cambelt-K

IF! weather permitting you take the time to LOOK at the cyl head and valves. I.E. a FINE DAY Drop the belt-put the pistons ALL in the middle of their travel. rotate the cam and observe how number 4 cyl valves **rock**-one exhaust closing and one inlet opening they will be **rocking** EVENLY on number 4 cyl at no 1 cylnder TDC FIRING.(Triangle mark) and will be **rocking** evenly at no1 cylnder TDC no 4 firing (just off the dot mark by 12 to 16 degrees=ONE CAM TOOTH.and ya'll have Learnt something that actaully a LOT of mechanics don't know
snoopy221,
Oct 3, 9:43pm
But hey ya know one mark is on a high point-and one is on a low point-so UNLESS YOU MOVE THE MARK ON THE HEAD. how can they both time the same!
crzyhrse,
Oct 3, 9:43pm
It's not splitting hairs. It is either is opposite or it's not. In this case it's not.
Good luck, punk.

I had to read that a couple of times but i think i know what you are getting at, what you want me to do is observe that the no4 cylinder is rocking while no1 is on its power stroke, yeah i already knew that stuff, thats how i set my cam timing on my triumph as it had no timing marks what so ever, but yeah, Ill check it all over. weather permitting
snoopy221,

End of the day nissan used the same camshaft pulley for 3 diferrent engines and marked it accordingly. You have used the better of the INCORRECT marks LUCKILY. However if you had timed it correctly yourself by the correct age old method-well.- . [At least ya now KNOW why there are 3 timing marks-but only ONE IS CORRECT] Fords are .ab and c.LOL
supernova2,
Oct 3, 9:56pm
Gees this is getting complicated.TDC firing no1 the triangle mark on the cam lines up with the dot/dimple/mark on the cylinder head.What I called the keyway is called a "knock pin" by nissan and thats the round pin in the cut out on thge trinagle plate on the cam bolt as in snoops pic.The engine in snoops pic is the e15.Im sure there are timing marks on a triumph but would have to dig out my book.Could take a while as havent used it for 29 years since I last had2500PI
ginga4lyfe,
Oct 3, 9:59pm
it should be correct as it is really, the old belt came off and i didnt move any pullys while installing the new belt and tentioner, only one way to find out though
snoopy221,
Oct 3, 9:59pm
Im sure there are timing marks on a triumph ***Nods head in agreement**-passes JD's. [Checks profile.incidentaly the subaru referred to was in rotovegas-LOL]
