Question about 1989 Honda CRX

1 Answer

Cam positioning Need to know the position of the cam in accordance with the crankshaft on a 1.5. Head was removed for maching and milling and cam was removed as well so I need to figure out how to set the timing on the camshaft. I allready tried TDC on #1 piston(on compression stroke) camshaft pulley at the "up" position and the rotor on the distributor pointed to number 1 plug wire on cap and motor turns over and has fire but will not start. Please help me figure this out!

My husband is trying to fix my 04 dodge ram 1500 4.7l, the computer says to replace the crank sensor and or cam sensor. the crank sensor was replaced a month ago. it wont stay running. but he doesnt know...


On the 4.7L, the cam position sensor is located on the right cylinder head (thats the passenger side) toward the front below the valve cover gasket. Not on the front of the head but on the side where the exhaust manifold is attched at the forward end of the head. The crankshaft position sensor is located on the same side (right) but is at the opposite end of the engine between the bell housing and the block. The crankshaft position sensor can be replaced without removing the engine or transmission, it just looks tight. Also, on the crankshaft position sensor, it slides out of a rubber gromet. Here's a few pics to help. hotrodshop.gifhotrodshop_0.gif

Need to know how to set the timing on a 1990 honda accord ex


Pop out the spark plug in number 1 cylinder. Drop a long 1/4" drive extension in the cylinder. Turn the crankshaft until the timing mark on the crank pulley meets "0" and the extension is at it's highest point of travel. This is your correct crank position for timing. Pop the cover off and find the indentation or arrow on the outside front of the cam sprocket and align it with the corresponding mark on the head or cam cap. If you're only talking about using a timing light, then lossen the distributor bolt at it's base and turn the distributor until the mark is at 0. Engine must be at normal operating temp.

I have a blown head gasket. i need to know if i need to remove the air intake to take off the head to get to the gasket. thank you


yes, air intake, intake manifold and exhaust manifold. This is not a job for a novice. If engine has overhead cam, then cam chain/belt must also be removed. Rocker arms must be loosened to allow valves to close. Note position of timing gear in case cam rotates while chain/belt is off. Camshaft must be properly timed to the crankshaft on reassembly.
Head should be checked for warping and cracks. Follow torque instructions carefully when reinstalling the head.

I need a diagram of timing chain replacement Thank You


During most engine rebuilds, a completely new timing assembly should be installed. If wear exists on any component, replacement of the entire assembly is necessary. Wear in the chain, gears, or sprockets means a timing lag, which results in poor engine performance.
The timing chain or belt is generally installed with the gears in their correct positions. Before installing a new chain, soak it in oil.
OHC (Overhead Cam) Engines
Some OHC engines use a chain drive; others use a belt drive. Removing the cover on some OHC engines that have timing chains is more difficult, because the cover often fits between the oil pan and the cylinder head. There are special procedures for replacing cam timing components in these engines.
Before a chain repair job, perform a leakage test on non-freewheeling engines to check for bent valves, so that an accurate repair estimate can be made.
OHV (Overhead Valve) Pushrod Engines
On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another. NOTE THIS IS FOR 2WD 4.0

Need cam timing specs 22r toyota truck


there will be two highlighted or dotted chain links for the camshaft and one for the crankshaft gear, position cam dot/TDC indicator in the 12-O clock position, the two dotted links should be on ether side of cam dot, turn crank dot to the 6-O clock position and line up highlighted link with dot on crank gear, if timing cover is on, then make sure cylinder 1 is at TDC when the two links are at 12-O clock.

well not sure exactly why it wont line up use something to turn the crank and cam to appropiate position start sliding crank gear until cam gear is touching then start to push both at same time make sure your crank key and cam pin are bothin place On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another.

Still need advice


Turn crank so that timing mark on front pulley is at 0 degrees.
Remove the timing cover and you should see a mark for the cam to line up with.
You want the cam lobes on No.1 cylinder to be pointing away from the followers wether they be rockers above cam or buckets below. This will be the compression stroke.
Once the cam timing is set you can recheck the distributor. It should point to No.1.
