Question Answered: 

An occasional ticking or rattling noise from the camshaft hydraulic valve lifters (HVA) may occur during cold engine starts, due to frequent short - distance driving, or the noise may occur for an extended period of time even though the engine is at operating temperature. Improved parts were phased into production beginning on 10/1/2008 and fully implemented on November 31st 2008.

We do exhaust here at CarMasters Virginia Beach 757-456-0722. We often get the hard to do jobs from the exhaust shops when bolts have broken off and they do not want to or do not have the ability to deal with the more in depth jobs, If it is a very easy exhaust repair in addition to CarMasters Mitches muffler and brake in Norfolk is very reasonable as well, Ask for Michael 857-5738

Question Answered: 

When sitting still and revving there is no load (or little) on the engine and transmission, also ignition timing problems (they are computer controlled) can also cause a rattling under load. At CarMasters we depending on the problem can install a electronic chassis ear on vehicle during road test or operate on a lift with one technician under vehicle listening while and other is operating the engine and throttle from drivers seat to identify the source of noise/concern

Question Answered: 

Sounds like your friction is not being applied properly, which can be caused by control/apply electrical/mechanical components such as computer, solenoid valve, valve body, pump or can also be caused by worn out friction as well such as clutches. Many control problems often can be corrected quicker and for less cost, whereas pump, friction type problem would require transmission removal and overhaul or replacement. Need to start by having vehicle towed to a quality repair facility for diagnosis.

Question Answered: 

Besides owning a shop, I also go into all the dealerships and most of the independent shops from Kitty Hawk NC to southern Maryland as an inspector/investigator for legal arbitration, warranty, insurance companies, BBB and national corporations/manufactures. I frequently have seen timing belts breaking well before the 90K to 105K mileage recommended by most manufactures (of course after it is out of factory warranty. The advantage to most manufactures to extend the maintenance on everything or to not even schedule change/replace (now most things only say inspect that in past said to change/replace)anymore is so they can help sell and market their products by advertising a lower cost of ownership by eliminating maintenance especially if it has little effect on the vehicle until after the factory warranty is expired. I recommend my family and customers change their timing belts between 60K to 70K changing components every other time. I have seen many failures starting at 72K and of course out of warranty. Please call Roy 757-456-0722, if you are due for change and make sure to let him know if you would like a free loaner vehicle while yours is being serviced, Jim

Question Answered: 

You can try (very dangerous)some flammable spray like starting fluid or brake cleaner, spraying lightly while cranking and if engine runs you confirm that you have a fuel problem. This should is normally only done with professionals as it is possible to have a back or misfire that can start a fire. If engine runs on a shop type fuel supply then as pushrod suggested you may have a fuel pressure problem which could be a electrical problem with pump or injectors or mechanical problems like filter, pump, pressure regulators of injector(s). If you still can not get going you can call Roy 757-456-0722 for to arrange a diagnostic and request/reserve a free loaner/rental vehicle while being diagnosed/repaired.

Question Answered: 

In addition to owning CarMasters Automotive and working on Mercedes I also am contracted as an expert to go into the dealerships and other repair facility to perform inspections/investigations for legal arbitration, BBB, warranty and warranty/insurance companies with the majority throughout the years on Mercedes. I would agree on many problems on the 00-03 CL 55 AMG (those years average 400+ TSB), the 00-03 CL600 also has its share of problems but only about half that of the 00-03 CL 55 AMG in my experience. Recommend before you purchase a pre-owned vehicle let us check it out so you have a better idea of and current but not obvious problems before you purchase 757-456-0722

Question Answered: 

Recommend clean area around the leak, then monitor to determine the source of the leak. Sometimes it may be helpful or even necessary to add UV dye and use a UV light to find source of the leak. Leak could be from the valve cover gasket replaced already. I head and valve cover not properly cleaned of gasket not aligned properly new one can leak. How much crankcase pressure from blow-by does your engine have? Also if your PCV is not working properly or your engine is worn out (piston rings/valve guides) you may be over pressurizing the crankcase which will cause properly installed gaskets and seals to prematurely leak. Also if valve cover was over tightened that can crush gasket or bend/break/warp the cover causing leaks. If you would like your engine professionally check please call 757-456-0722
