Can timing chain affect compression?
Even a single-tooth slip can severely affect engine operation. You can also confirm a timing problem by checking engine compression. If the valve timing jumps, you’ll get little or no compression equally in all cylinders.
Can a bad timing belt cause no compression?
If the timing belt were to be broken or damaged, the camshaft would no longer be able to turn anymore. This means it cannot open or close the exhaust valve or intake valve properly. As a result, the combustion in the cylinders will be ruined and no gases can get released. So, you have low compression because of it.
Will compression test show bad timing?
Yes the valve timing must be correctly set for a valid compression test. Compression happens as the piston moves up during the compression stroke AND the exhaust & intake valves are closed.
What causes a problem with the timing chain?
Timing chain problems can appear as noise or engine performance issue, or both. Whether the symptom is noise or engine performance the root cause is always caused by the timing chain tensioner, guides or a worn and elongate chain.
Do you have to drop the cradle for timing chain replacement?
However given the (high) number of timing chain replacements you can rest easy knowing the dealership has had lots of experience doing such a job :. It looks like the whole engine cradle will have to be dropped to get the work done , just look at how little space there is in the engine compartment .
What to do if your timing chain rattles?
To prevent the timing chain from rattling over that long distance, they incorporated plastic guides and sometimes even hydraulic tensioning devices to keep the chain at a constant tension. When new, the tensioner and guides work well to keep chain noise to a minimum.
Where to put the timing chain on a traverse?
Remove EN 46105-1 or 48383-1 from the left bank. The engine will need to be rotated 115 degrees clockwise for stage two timing. The crankshaft marks should align dot to dot. (Fig. 5) Tool EN 46105-2 or EN 48383-2 should fit easily on the rear of the cams on the left bank of the engine. EN 48383-3 should be installed on the right bank, or bank 1.
