2000 c230 kompressor rough idle and ticking11/14/2023 Oil is too thin when hot and running out of the HVA? Oh and I decided to test the old fuel filter now that it had dried out. Does anyone know if there is a port in the cylinder head to check oil pressure? I did notice the tick noise seems to be predominately when the engine is hot. we'll see if the flush procedure can fill them. Makes me think that there must be some debris in the HVA's. Assembled the car and started it and the chain must not have been right. Finally got around to pulling the lower timing tensioner and guess what. Voltage regulator appears to still be doing its job. The bearings in the alternator are going it has been confirmed. The synthetic is making quick work of what little debris was in the engine but still have the tick noise. I decided to cut it apart and it was full of what looks like carbon deposits. I remembered and went to pull the old one. So upon the last oil change, super genius forgot to put the new oil filter in. Rough idle is the least on my worry, ticking noise is kind of concerning.Īnd there is no cel and no codes stored (from stomp test) Timing tensioner bad? lack of oil to valve train? Cats bad? Or could this all be caused by the OSV? My first thought is bearing knock (as I am a pessimist) please tell me I am wrong. passengers side, one at 210, rest at 205. again engine warm WOT.Ĭompression test yesterday drivers bank 190 on all. Passengers side, 1 cylinder at 205, rest in neighborhood of 195. compression test on as arrived engine all cylinders on drivers bank 190 PSI, warm w/ WOT As rpms increase ticking will increase then disappear at approx 2000 rpm. under load ticking is tied to acceleration, however when spirited acceleration tick disappears. The ticking sounds like passenger side of the engine. No leaks (At least fluid) (haven't been able to find vacuum leak) fuelįilter needs replacing, again on order. However when the windows are open you hear nothing, OSV needs to be replaced part is on order. Just noticed a ticking noise that can be head in the car with the windows and doors shut while running. Some mornings it fine (when cold), some afternoons its fine.(ambient warm) Rough idle has progressively gotten worse. I’d like to know how many people have had this issue and what you did to get rid of that tapping noise or at least make it quieter.Here are the list of symptoms and work performed. Right now I’m running Castro Synthetic Oil. He said his Tundra runs quieter on Valvoline synthetic oil. I talked to a customer service guy for Toyota about it and said using different oil might help too. Someone also said I could run Miracle Oil in the oil and engine and that it would help remove the varnish. I did add Lucas Oil for synthetic oil and it was noticeably quieter. I’m wondering if there are ways to reduce the noise. He said these engines tend to get a varnish build up on the fuel injection and valves but it nothing to be too concerned about. A Toyota Dealer mechanic told me that it’s fairly common for these engines with 30k+ miles. The one I’ve had the most concern about is a light tapping/ticking noise coming from the engine. But there are new sounds that I’m not accustomed too. So I replace her with a 2016 4Runner TRD Pro. But my last faithful steed has gone to pasture. I owned a nothing but Isuzu Troopers the last 25 years.
