Tdc @ 1cyl. cam shaft has triangle stamp mark on face of the gear.both valves for # 1 should be closed in compression stroke and triangle should be pointing at left side top of head(9 o'clock) on the silent shaft and oil pump pulleys both marks must align with each other , use a metal rule for a straight edge.it would be wise to purchase a haynes manuel for your vehicle.this manuel gives you illustrations and step procedures to align all components on your g63b engine ....chris

What is the fuel pump pressure for a 1990 geo storm 2+2


storm what engine? 4xe1 or 4xf1 SOHC or DOHC (twin cam)?
its really an Isuzu Impulse in snack skins (badges)
does test fuel run engine? that is step 2.
if the cam timing belt slips, the DOHC goes boom.
the SOHC engine belt slip,cause no starts, due to huge
compression drop, and fails the test fuel tests.

SOHC, keyon, 30-46PSI
same for both. engines
but as all mPI engines it drop running at idle.
and rises at WOT> (FPR actions most work right running) ask
but its no running
ever do a 60,000 interval tuneup with a new cam belt.
no?

I have a 1999 plymouth breeze and replaced water pump and timing belt due to pump locked up and all the teeth gone off belt now. 2.0 SOHC that after setting belt and timing correctly the car wont start...


In general, backfiring indicates the cam, crank and ignition are out of time or out of phase. The timing marks on the crank and cam just line up the timing of the cam and crank. The alignment of the spark with them has to be phased at the right time too. Check the manual for how to set the distributor timing after an engine repair

Setting of timing chains


Get Ford timing tool kit, part = otc-6488 (For about $119 USD on eBay)

4 timing chains (3 front including the optional balance shaft chain + 1 back)

2 cam guides (1 front + 1 back)

2 oil tensioners (1 front + 1 back)

1 jackshaft tensioner (1 front)

1 jackshaft guide/cassette (1 front)

1 balance shaft tensioner (1 front) (will probably be ok, so dont replace it)

1 balance shaft guide (1 front) (will probably be ok, so dont replace it)

new sprockets + bolts + gaskets etc.

new spark plugs + throttle body cleaner + lithium grease spray + oil change

head gaskets


some of these parts (the front stuff) can be obtained as a primary timing chain rattle noise kit Part# = 2u3e-6d256-** ab for 4*4 & bb for 2*4.

The kits also have later part numbers for us$ 76 @ http://www.fordpartsonline.com


My parts order (without the balance shaft stuff) was:

$76.04 KIT-TENSIONER TIMING 2u3e-6d256-ab

$47.93 Engine, Camshaft and timing, Timing chain, TIMING CHAIN, Explorer, Mountaineer, Rear - 4.0L SOHC - 4.0L SOHC

$57.36 Engine, Camshaft and timing, Chain guide, CHAIN GUIDE, Explorer, Mountaineer, Jackshaft To Cam - 4.0L SOHC - 4.0L SOHC

$103.22 Engine, Overhaul gasket set, OVERHAUL GASKET SET, Explorer, Mountaineer, Upper (Valve Grind) - 4.0L SOHC - 4.0L SOHC

$28.93 Engine, Camshaft and timing, Tensioner, TENSIONER, Explorer, Mountaineer, Upper - 4.0L SOHC - 4.0L SOHC

Its worth mentioning that this procedure is not enjoyable at all and should be undertaken with at least 8 full days to completion (I recon you could do it in half the time the second time).

It is basically on entire engine re-build with both heads off and the engine out of the vehicle.

It is not possible to do the rear chain or sprocket with the engine in the car as the flywheel needs to come off + at least 1 head, but it is possible to do the front primary chain and or front cam chain with the engine in the car.

You will be a ford exploder and timing expert after you do this - the main reason should be the love of your American built vehicle. Its a solid car - except for the plastic guides!

Disclaimer Note: This is how i successfully did the job, but i am not a ford mechanic and don't hold me responsible if this does not work for you.
Timing Overview

A Small Sprocket on the crank turns a larger (2 to 1 ratio) jackshaft sprocket that is in turn connected front & back to the 2 camshafts.

Thus a 360o turn of the crank will turn both the camshafts 180o.

Firing order is 1-4 2-5 3-6, Right side numbers 1,2,3. Left Side = 4,5,6.

At TDC pistons 1 & 5 are fully raised, thus 1 is about to spark & 5 is evacuated.

The engine will turn freely (no piston to valve contact) with the cams 180o out, it will even run (roughly) with 1 out 180o, any other settings may cause major damage to the valves.

The 2 cam shafts come with timing markings, "yes" real timing marks that anyone can use (even without special tools) to ensure correct timing.

The way to time it is to ensure both the off centre cam shaft slits are level/flat with the head.

With the engine at TDC both the cams need to have the off centre slot in the same position either up and level or down and level.

It is super critical that both the camshafts are 100% in sink with each other, i.e. not a few degrees off, the engine computer can compensate for crank timing but not engineering failure.

Be warned the camshafts can turn easily fast & hard by themselves as a few springs are compressed at TDC, I got my finger jammed and its still healing + if the engine is not at TDC you may damage a valve.

Now heres the hard thing that you will need special tools for - if you need to change the timing, you will need to be able to undo the cam sprocket bolt on both cams & these are done up real tight.

There is a tool that you attach that has 2 pencil thick shafts that fit into the sprocket and prevent it from turning - then you need to put about 90Nm of force on the bolt (remember the rear one if LHT)

For the $money$, its well worth getting yourself the tool kit - it will save you hours in the long run. Search eBay for otc-6488 should be US $119 - then sell them again for say $100.

There is also a tool version of the oil tensioner in the kit that screws right in and puts the correct amount of force on the chain + guide, to enable you to do up the cam bolt with the chain and sprocket in the right spot on the cam.

After replacing a timing belt and componets, how do I set the timing on a 1997 Ford Escort LX with a 2.0L single overhead cam, std emission engine with A/C and a 5 speed manual transmission?


If you mean valve timing (there is no adjustment for ignition timing), see diagram below from autozone.com. Make sure belt is tight on the right side with gears in these positions:


Fig. Fig. 11: The timing marks on both the camshaft and crankshaft pulleys must be aligned like this before removing or installing the timing belt-2.0L SOHC engines ea0a8b0.gif

I have a 1994 eagle talon i replaced the water pump and put on a new timing belt and i can not get the timing right i have tried everything i know what could i be doing wrong? I have made sure the number...


I'm looking at the manual (68030 Haynes) and it shows that if you have the DOHC you make the 2 marks onthe camshafts meet in the center.

That would be at the 3 o'clock position for the left one, and 9 o'clock position for the right one. the crank sprocket and oil pump sprocket align exactly with the timing marks.

NOW, on the SOHC single cam pulley, crankshaft and oil pump pulley all are to be aligned with their index marks, centered, and the balance shaft is to be with the weighted side down to prevent vibration.

I've done the SOHC and the marks are fairly centered when instlalling. Once you've got the belt on in either engine, you should rotate the engine in the normal direction for 2 full revolutions and recheck the timing marks at all positions, readjust, rotate and recheck until set on the marks.

Good luck,

How to set timing marks when changing the timing belt 1995 kia sportage 2.0liter


There is a DOHC or SOHC (double or Single overhead cam engone. Both are Similar. Both have a notch on back side of crank pully that aligns with a tab on engine just above crank pully looks like a triangle with the tip near crank pully is rounded off. SOHC engines have an arrow on cam pully that aligns with a point at top of timing belt rear housing. about straight up at top of it. DOHC have an I and an E on the cam pullys I for INTAKE and E for EXHAUST. the I and E match up at same type points on top of rear Timing belt housing. When installing belt make sure you do not move pullys. put belt on starting with cam shaft (s) then down to crank on tension side which looking at motor will be the right side or Clockwise direction keeping it tight no, or EXTREEMLY little slack. then back up around tensioner. Tensioner should be the last pully to go around. Once on make sure timing marks still lline up.Adjust tensioner and. rotate engine BY HAND 4 times and re check marks.

not true. SOHC 4.0 tensioner and rails fall apart, allowing the chain to slap and do damage, or even break. book it. in order to replace rioght side cam chain and tensioner, the engine MUST BE REMOVED! if it has balance shaft chain in oil pan, there are a total of four chains in this engine.

I need to find a timing belt diagram for a 1994 mitsubishi galant


Your car will have the 2.4L SOHC engine in it (AKA 4G64). This manual will show you how to replace the timing belt (and more). Timing belt procedures start on page 33.

http://www.scribd.com/doc/4570538/Mitsubishi-4G63-4G64-Engine

(P.S. this manual also includes the 4G63 engine, you can identify your engine by looking at the procedures for the Single OverHead Cam[or SOHC])
