I have an 03 vw jetta 1.8 turbo. The timing belt has broken according to the mechanic. My question is this what is called a "contact motor" which requires a lot more work such as head work etc....


You have a contact or interference engine. This means that there is not enough room between the top of the piston when it is all the way up for the valves to be open. What happens is they get hit by the piston and they bend or break. You will have to take the head off and send it to an engine rebuilder. MAKE SURE they know Volkswagons or you will likely be taking the head off again and sending it back out. Normally valves and valve guides need to be replaced, you are looking at about $1200-$1500 for a proper job. Also you will need new head bolts, VW head bolts are not deisigned to be reusable. (Been there, done this).
You might be better off looking in a scrap yard for a replacement engine. , or a head.

A pulley broke as I was driving on the highway last week, which caused the timing belt to come off. When the pulley broke, the bolt snapped off, flush with the block. The mechanic spent hours trying to...


Hi Nancy,

Where do I start with this one?...There are several things that I see that is wrong with this picture.

OK. To begin this thing, I think I should first say that although you did not mention which engine your 1994 Ford Probe is equipped with, it makes little difference because BOTH of the engines available for that year and model (4 cylinder 2.0L (VIN code [A]) and the V6 2.5L (VIN code [B]) are what is called "interference engines". This means that if the timing belt breaks or comes off for any reason with the engine running, The pistons WILL contact the valves and damage to the valve and possibly the piston will occur.

You probably will not notice or "hear" when this happens. I have actually had one do it in the shop while I had my head under the hood. It made a single, loud "POP" and that was it. Once the valve got bent over inside the cylinder, the piston no longer made contact. However, the damage was done!

Then I have a serious problem with the way the mechanic handled this one.
When an interference engine loses a timing belt, the FIRST thing the mechanic should have checked for is damage to the engine due to piston/valve contact.

This is done by removing the cams from the cylinder head(s) to allow all the valves to close and perform a cylinder leakage test to identify any cylinders with bent valves. Removing the cams is also REQUIRED to get the engine back into time anyway, so this is not a waste of labor.

The mechanic should NEVER have attempted to rotate the crankshaft or the camshaft without the timing belt in place. If there was any possibility that there was no damage done when the timing belt broke, that chance just went down the drain. The fact that the cams rotated DOES NOT mean that there is no damage to the valves.

Then comes the question of the broken bolt. Yes, I can see the possible need to remove the engine to get the bolt removed. If he knew what he was doing, this should be nothing but a thing. You do not trash an entire engine over a bot that is broken off in the block. If the piece cannot be coaxed into simply unscrewing from the block, there are other alternatives, including drilling the hole out oversize and installing a helicoil to restore the threads in the block.

Then with all of this said, I would have to ask about the general condition of the REST of the vehicle. After all, we ARE talking about an 18 year old car here. Is the car itself worth the expense of removing this engine to repair it. Is it worth the cost of possibly having to replace a piston or cylinder head? Only the customer can make that judgement, however, the mechanic should ADVISE the customer in situations like this, based on his overall evaluation of the ENTIRE vehicle. But then again, this should have all occured LONG be fore the engine was removed in an attempt to drill out the bolt.

Broken crank shaft the mechanic said he wont be able to know if valves are bent until he puts it back together of course he said the valves are bent. How difficult is it to replace valves?


Find another mechanic. you got ripped off. A broken crank does not mean you cant check the valves. Called a leak down test. This engine should have been replaced. And probably still should. Your talking about a $1500.00 job.

Head Gasket?? Valve cover Gasket???


most likely it is the valve cover gasket. it covers the valve train where there is alot of oil to lube the top of the motor. if the head gasket was leaking it may have more signs of running poorly. also having coolant leaks also. so i will have to say valve cover gasket. now usally you may have a oil burning smell with it depending on the area of the lek but not always.

the valve cover can easily be seen when the hood is open. it is right on the top and where it meets the clyinder head is where the gasket is and the leak can be seen.

if you have more question please ask.

The mechanic should use or do this ,"engine lubrication ".cleaning the engine while fixing the engine .If the problems in the multi cylinder, then its the piston and the piston rings. Replace the destroyed or worn out piston rings.then check the crank shaft and the cam shaft for for assurance .then set in timing for ICPE ,icpe is the intake, compression ,power and exhaust.then check and arrange the engine valve.the mechanic should use filler guage for the valve .the misfiring ,check the carburetor or fuel pump throttle.may be its stuck.In High speed auto-diesel mechanic , trouble shooting is what we always encountered while studying .But its not just engine but even car electrical problem.headlights , fuses and other electrical parts of a car.But its seems that the problem of the car is not electrical problem sir , good day sir.

I need a new engine head


Not a recall. Find a head in the junkyard and have the valves reground.

Engine knocking


Hi,
Good news is - I don't think you need a new engine.

As there are many moving parts that could create a knocking sound, it usually needs careful inspection to identify where it is from.
I will give a list of some of the causes and remedies. Yours will probably be one of them, but unless I was there - it could be any.

Loose exhaust component (causes rattles and thumps) - replace parts or joints.
Loose Engine mounts - Engine will move about a lot more than normal - Replacement of mounts.
Fraying Belts - causes continual ticking or slapping - Replace belts and check tension.
Timing is off - bad running, lack of power, pre ignition or knocking at low revs. Check timing belt - Replace, Tune engine.
Cracked valve - slight misfire worse at low revs - Replacement valves.
Clutch Problems - Broken spring or loose bolt - Check clutch plate - replace clutch plates.
Older engines - often accompanying smoke -
Broken Piston ring - continual ticking or occasional misfire - Replace Piston rings
Worn Piston bearings - Piston Slap - Replacement of all piston bearings.

Transmission Problems (only heard when in gear or with clutch out) - Broken gear teeth or worn bearings - Replacement of Transmission or rebuild.

Some of these remedies require engine removal and strip down, others are a simpler fix.
