Question about 1986 Honda Prelude

2 Answers

Engine will not start 2.0FI

Ok started with a head gasket, no big deal replaced, installed new timing belt. set cam marks and crank marks at TDC. started and ran for about 10 min. Engine stalled and would not restart. Re-checked timing marks all fine. timing pointer is at 15. Checked fuel rail, no fuel. checked voltage at fuel pump. no voltage! Put 12V power to pump and works fine. plenty of spark. So I am looking next at the ECU. but In the panel behind the rear passenger seat, the ECU does not have any lights or flash any codes. Also this is a new car to me and not sure if the seat belt audible alarm and dash light flashes 5 times. Not really sure if that is a code or not. Any help would be a great help.

Thanks

Check the fuel pump relay it is located in the junction box under the hood. if you have no power to the pump that is because either the relay went bad or you triggered the fuel cutoff switch and need to reset it.

I'm replacing the head gasket on a 95 Nissan altmia 2.4, do I need to put the engine at TDC before removing the cams and chain?


its a good idea to set the engine at TDC before disassembly. note the location of timing marks on crank and cams to familiarize your self when you go to re-install.

Resetting timing after replacing head gasket


Do you have the timing belt on and the tensioner set correct? If so, just rotate the crankshaft around until the notch on the crank sprocket is lined up with the pointer on the oil puimp housing (TDC). Now the camshaft sprocket's notch or pointer should be at the top and exactly in line with the mark on the rear timing belt cover. If it's not correct, you'll have to release tension on the belt, remove it, and set the camshaft to the mark. But before you do that, turn the crankshaft back (counterclockwise) just three notches. Then you can turn the cam to line up, then return crank to line up, and continue with belt installation, setting the tension, and re-checking timing marks after rotating the crankshaft a couple of revolutions. Once you know the timing is set to TDC, no further timing adjustments are possible, because the computer controls timing. I don't know how important it is, but just to let you know: Chrysler recommends after belt removal or replacement that one perform the "crankshaft and camshaft relearn alignment procedure" using the DRB scan tool (Chrysler's scanner device) or equivalent scan tool.
And the firing order on all four cylinder engines is the same: 1 3 4 2.
I hope this helps you out. Cheers.

I replace timing belt but cant set timing


Hi Robert, It would help to know what engine is in your vehicle? A rule of thumb way to set up the valve timing is as follows. Rotate the crank shaft until the crank shaft mark is about 90 degrees from TDC. This will protect the valves from damage when rotating the cams to align them. With the tappet cover removed rotate the cam shaft or shafts so that the number one cylinder is on compression (both inlet and exhaust valves fully closed) and the last cylinder in line on overlap, Look for adjacent timing marks on the cam gears and somewhere close to those look for the alignment marks (maybe notch marks, holes or indented match marks). (Some manufactures use the machined gasket surface where the tappet cover closes onto the cylinder head). Look closely for the static mark on the cylinder head and align the cam(s) to it or them. Once completed, set the crank at Top Dead Center and look carefully for a timing mark which aligns with the gear and set them. Fit the belt so the marks align when the tensioner bearing is released and presses the belt under load. (follow the manufactures recommended tightening instructions.) . (Remember never to crimp a timing belt, if it has been, throw it away and get another, even if it is new!) If the belt snapped and that is the reason for replacement, internal damage may have resulted inside the engine. A snapped belt may cause damage to the valves, the camshafts, the cam shaft caps and to the pistons. If the engine turns much faster than expected and sounds as if there is no compression, you have problems! (Those I've just mentioned. I hope not for your sake. best of luck Regards John

How do i set the valve timing if i cant see the timing marks on a VW 1.8 20valve golf cylinder head timing chain , i can only find the one on the belt side i have put the cam on TDC for the ex-valve but...


The 2 cams are linked with a chain at the rear of the cylinder head.

The cams need to be set so the slots on the chain sprockets line up with the cam tower caps with 16 links between cam caps.

You cannot see the front crank pulley tdc mark so you need to lock the engine at tdc with a screwdriver jammed into the timing hole on the bell housing after setting engine at tdc or use a DTI
to check to tdc in the #1 spark plug hole.

If the cams have not been disturbed you only need to set the belt cam sprocket to the mark and crank to tdc.....all this means pulling the core support into the service position so the belt tensioner can be locked down and/or doing a complete belt job along with a coolant pump if over 70,000 miles..

I replaced the head gaskets on my subaru forester and now it will not start posibble timing prob


It sounds like you might have it a little out of whack, probably a good thing did it didn't start, you could have messed it up bad. Why did you replace the head gaskets?? Was it overheating? Were the gaskets bad? Did you mark the cams and belt before you took them off? Did you get a new belt? I would pull the spark plugs out, take the rocker covers back off, take the belt off, watch the cams, bring them around to their mark, bring the crank around to it's mark, make sure it is easy to spin, if not, you are hitting something. get the crank and the cams aligned on their marks and put the new belt with the marks on the belt aligned to the marks on the cam and crank. If the belt doesn't have marks, get one that does. Or put the marks on there. Check the old belt and see if it has marks on it. They help a lot. Once you get the belt on there and the tensioner set, spin the engine by hand and make sure it spins free, It should come around to the TDC mark on the crank again and again. Unless you forgot to hook something up, like the coil pack or a couple wires here and there. Check it out, Hope this helps.

How do i set the timing after replacing the cambelt.


Put the engine at TDC compression stroke , Thats when the valves are both closed on No 1 cyl and the piston is on its compression stroke .then align all cam and crank marks. set dizzy on No 1 cylinder (rotor pointing at #1 plug wire) . rotate engine 2 revolutions and recheck all marks. Fire away

Replaced timing belt need do you start at TDC to


For all timing belts you should start with the crank sprocket pointing at TDC and the cam sprockets pointing at their designated marks.

You should be able to mark the old belt and and put corresponding marks on the cam and crank pulleys, then remove the old belt and transfer the marks to the new belt and install it.

Personally I would buy a manual as this would provide you with a step by step guide to performing the repair.

I am not positive that this is an interference engine, it looks like it is to me. If you are not accurate in your timing you will cause severe engine damage.

1989 Isuzu pickup how to align timing marks on cam and crank?


The Isuzu is a strange animal-when you do the timing belt you set it with #1 TDC "BUT" the distributor is timed with TDC #4 I found this the hard way and finally had to buy a cd with the procedures on it. Send me an e-mail address and I will forward the associated pictures &
info to you.

TIMING BELT & SPROCKETS R & I
NOTE: Some procedures may differ slightly due to engine
construction.
Removal
1) Remove all necessary air ducts. Position No. 4 piston at
TDC of compression stroke. Align timing marks. See Fig. 2. Remove fan
and fan shroud. Remove belts. If necessary, remove radiator and
splashguard.
2) Prevent engine from rotating and remove crankshaft timing
pulley retaining bolt. Remove upper and lower timing belt covers.
Remove spring from tension pulley. Loosen adjusting bolt and move
pulley toward water pump. Remove timing belt.
CAUTION: Ensure pistons are at TDC when rotating camshaft or damage
may result.
Inspection
1) Handle timing belt carefully. Avoid twisting or kinking
belt. Do not allow belt to become contaminated by water, oil, dirt or
other contaminates. Inspect belt for cracks or damage. If necessary,
replace.
2) Measure tension pulley spring length and force. Spring
length should not exceed 2.76" (70.2 mm) and spring force should not
be less than 197-347 lbs. (27-48 kg).
3) Replace tension pulley spring if not within specification.
Installation
1) Pull tensioner fully toward water pump side and
temporarily tighten retaining bolt. Ensure No. 4 cylinder is at TDC on
compression stroke by rotating crankshaft until keyway aligns with
mark on front crankshaft seal housing (12 o’clock). Rotate camshaft
until timing mark on cam gear (arrow) aligns with mark on upper
camshaft cover (notch). See Fig. 2.
NOTE: When timing marks are aligned as stated above, No. 4 piston
is at TDC on compression stroke.
2) Position timing belt over crankshaft sprocket, oil pump
sprocket, camshaft sprocket and tensioner in that order. Ensure belt
is positioned in sequence given and without slack between sprockets.
Loosen tension sprocket adjusting bolt allowing spring tension to
tighten belt. Tighten adjusting bolt temporarily.
3) Temporarily install crankshaft pulley bolt and rotate
crankshaft 2 complete revolutions in opposite direction of engine
rotation, until marks on crankshaft and front oil seal retainer are
aligned again. See Fig. 2. Loosen tensioner lock bolt, allowing
tesioner spring to fully adjust tension. Tighten tensioner lock bolt.
4) Install timing belt covers. To complete installation,
reverse removal procedures. Tighten all bolts to specification. See
TORQUE SPECIFICATIONS table at end of this article.
