Answers :

The head must be removed to replace valves, also the replacement of these chains requires allot of special tools to align the cams, without them you will bend the valves again, and most likely if the chain came off at speed the valves are bent, the only way to know is to repair the chain and run a compression test on each cylinder to see if it has bent valves.. the last guy that i advised on this same job and model trying doing the repair without the special factory tools and no service manual and bent a new set of valves, trust on this, it is not a job for the home mechanic

I have a 96 320 SL with a badly leaking frost plug at the rear of the head right up against the firewall. Instead of taking the head off and exposing myself to the can of worms in the valve gear, i thought i would take the engine out and repair the frost plug. Can you tell me if in uncoupling the exhaust/inlet side/radiator hoses etc there are any hidden traps for the unwary?

Is it possible for. Lifter to bend valves in stead of wrong valve timing on a Renault Clio 3 ?

And machanic said its fine only a lifter noise all he can find. 2nd


You are right to be suspicious of the answer that you got, the only way for valves to get "bent" is for them to come into contact with the piston(s).the lifters are run by the cam, which is run by the timing belt, (which was just "replaced" b ... 2007 Renault Clio 1.6ESP

Cold start misfire on a 4.7L. Seems to come in pairs - 1&2, 4&5, 3&7. Coils (on plug) have been swapped with no immediate effect. Both heads have been off, disassembled and thoroughly cleaned. Bank 1 head replaced with new valves, springs, camshaft, and 2 lifters and rockers. MAP at start hovers around 16 but is 22 after it has cleared up which usually takes 30 seconds or so but could last up to 5 minutes. Tested MAP sensor and found it to be accurate. Compression is erratic but usually around 1

I have a 98 gmc 2500, w/ 454 engine.. Recently the engine was making some major noise so I took off the valve covers to find that the pushrods were very loose.

I ordered a new set of lifters and put engine assembely lube on them. I then put the entire engine back together following closely the tork specs for everythin

1997 Neon- DOHC. My timing belt broke or came loose. I am told that this engine is an "interference" engine. Before I repair the bad water pump and replace the timing belt,,how can I be sure that the valves and/or pistons have not been damaged? Do I need to take the head off? Any other way to figure this out? The car is not worth putting a lot of money into it if the valves/pistons are damaged. Thanks.


Since the camshaft and valve train are not connected (by the belt) to the crankshaft and are most likely out of time, any rotation of the camshaft or crankshaft may cause damage to the valves. The safe way to go is to remove the camshafts and let al ... 1997 Plymouth Neon

I have a P0106 error code on my 97 Subaru Legacy Outback. I just had a valve job done on the heads. I put the engine back together and put it back in the car, taking great care in the process. All hoses and wires were reconnected properly. The car runs fantastic. The only problem is the "check engine" light, P0106 error code. Would the pressure sensor go bad all of a sudden? Is there something I missed?


Using a scan tool, watch the MAP sensor value with the key on, engine off. Compare the BARO reading with the MAP reading. They should be roughly equal. The voltage for the MAP sensor should read approx. 4.5 volts. Now start the engine and look for a ... Subaru Outback
