Hi friends,am planning to buy an OHC and found this in team-bhp. Hope this will be useful for everyone looking to buy an OHC..
1. Check the a/c compressor, it should not be making any unwanted noise. It is prone to fail after say 30-40k kms.
2. Check for any leak from the Steering Rack joint. To see this just open the hood and locate the Brake booster, which would be on the left side as you face the car, look below that, you will see the power steering rack and the driveshafts, take a look at the rack joint, there should be no leak.
3. Check the service history of the car, if not available, check for COMPRESSION. It should be upwards the 185psi mark on all cylinders, Ideally in Bangalore which is 3000m above sl, it should be around the 190psi mark.
4.Check for CEL (check engine light), make sure that the light does not come on.
5. Check for the O2 sensor, which is known to conk of on cars which have done upwards of 50k kms. The best way to check this is to let the car come up to the optimum driving temperature, which on the temp gauge is generally 2 notches below the half way mark. if the o2 is gone, the CEL will come on once the cat is heated up.
6. Likewise, make sure the the engine is not heating up, it should at any given point in time be below the half way mark, ideally 1 or 2 notches below the half way mark.
Apart from all this, there is nothing in particular for the OHC vtec. Just do a general check up like, turn the car lock to lock to see if there is any sound which is coming while turning or not (you should not hear any sound). Check for any leaks in the engine bay. Check the suspension. Look at the running board. Look for rust and stuff..
Hope this helps.
