Question about Cadillac SRX

2 Answers

I am writing asking for help to address what I consider an unacceptable response from a Cadillac mechanic when asked to evaluate a valve-like noise coming from my 2008 SRX Cadillac NorthStar VVT V8 engine. I bought the vehicle used from Sam Swope Cadillac, Louisville, KY, w/ 28000 miles. The noise was mentioned to the sales person. No action taken. I had left the car at the dealership overnight so the engine would be 'cold' when an "engine specailist" rode with me. On acceleration from the dealers lot, there was the noise I had complained about, i.e. a valve rattle-like noise. The response from the mechanic when I asked "do you hear that noise". His response was "I hear the usual noise of these engines". It was obvious the mechanic was hearing the noise. With further dewcrption of the noise by me, the same response was repeated. The mechanic did make an interesting comment: something to the effect that amounted to - 'this engine had been forced into the enigine compartment space'. I was left with no plan for any action from the dealership. The noise does lessen after the engine warms up, but is still there upon acceleration, but diminished. In my estimation, the noise is from one or two valves; and seems to be from the left bank. The tag on the engine reads: JCA. 1OJCA L081120036 12596983; date coded 04/21/08 08:54. Please advise me.

I have a 2008 SRX Northstar. It makes the same noise as yours on startup, it lessens as the engine warms up. You can hear it on acceleration. The noise is from the VVT setup. All of the Northstars do it. I wouldn't worry about it. Give it good oil - Mobil 1 preferred, good gas - premium if possible, mid grade if you must, regular-never. Take care of the engine and it will last a long time. I've had three of them. Never had a problem.

What type of gas are you running in the north star? what you describe sounds like a valve rattle from preignition what i would do 1rst is fill the car up with premium gas (93) octane it will be expensive but a lot cheaper than running to the dealership drive the tank till empty and then resume as you were if this solves your problem you just saved yourself a few hundred dollars if not go to someone like auto zone and have a diagnostic done to see if any codes are stored there may be something with the timing of the anti knock sensor could be bad i would try these steps first before spending all of my money at the dealership if all else fails you can call gm yourself and see if they are having similar complaints from other customers. hope this at least get you started on the right road.

I have a Cadillac CTS 3.6L the problem is I'm having it's misfiring in cylinder one I already replaced all spark plugs as well as coils and fuel injector It misfires from time to time

unless you have read the fault codes , I have to ask --how can you be sure that it is no 1 piston at fault
take it in for a compression test as the problem could be mechanical-- sticking valve , loose valve seat insert , hydraulic lifter sticking or pumping up , holding the valve open

My 1997 cadillac deville, northstar w/85, regular oil changes, burns almost 2 quarts of oil every change. It is not leaking.

If your car is losing oil, and if there is no evidence of oil leaking, there is no question that it is either losing it through piston rings or through the head (head gasket or valve guides).
Best thing to do is use a HEAVIER WEIGHT oil than specified for the vehicle when new, regularly monitor your oil level and be sure it never falls below one quart low, and consider having the engine overhauled when you start noticing a performance deficit or hear mechanical noise (such as rod knock) from the engine.

I'm considering buying a 1987 Toyota supra turbo. 81k miles. What major or minor issues can I expect or need to ask owner about ?

If you ask the owner for the faults he has had expect an out right lie as to nothing is wrong with the vehicle. With such low mileage better to ask why he is selling it. I suggest that the seller produces proof that he actually owns the car and is capable of selling it legally. Next take it for a good run ( not around the block) and be critical in listing all noises and problems you find. Next take it to a reputable mechanic for a frank appraisal of the faults and see what he comes up with. Any must do repairs should be deducted from the asking price as you will be stuck with that cost.. Considering the age and the listed mileage I am suspicious that the mileage has been tampered with as most cars average 15 to 25 k per year Be very cautious also because the parts supply for an 87 car has dried up and you will most likely only get second hand parts ( Panels)

They can be adjusted its the valve lesh you need to remove the valve covers and adjust the rocker arm clearance on most engines you don,t say what engine you have so ask your mechanic to make sure but all on one side sounds like an adjustment

Tapping noise when car starts

Sounds like it could be your valves ticking. Sometimes this is caused by oil not getting to the hydraulic valve lifters for a couple seconds until the oil pump can get the oil pumped up to the top of the motor where the valves are. You might consider asking your mechanic to run a slightly thinner weight oil in your engine on your next oil change. Also, be sure to get frequent oil changes with new filter each time.

Hope that helps!

Ticking coming from the engine

Hi, The noise may be due to an exhaust pressure wave that is migrating past the secondary A.I.R. check valves into the hose plumbing. The pressure wave produces an objectionable noise similar to valve train noise or detonation. The noise migration is due to system pressure imbalances and is not an indication of a component part malfunction such as faulty check valves.

Perform strategy-based diagnostics to determine the source of the engine noise. For evaluation purposes. disconnect the A.I.R. crossover tube (3) and cap off the check valve outlet nipples (1 and 6). If this is the condition responsible for your concern, the source of the noise has now been eliminated and can be confirmed with a test drive.

Take care

Service ride control

the light can be reset using a diagnostic scan tool. perhaps the mechan did not have the right interface for your vehicle. the body control module is what is responsible for this system and not the ecm( engine control module)now the only way for sure to know if the mechanic actually fix the problem is to check if the parts needed were replace under the vehicle ie the the ride control servo motors on the rear axles and/or leveler valve
