Hi all,
I have a 2007 2.2L SX Sante Fe, just recently had timing belt done, all serpentine belts and associated tensioners replaced. Car has travelled 227,000 fairly trouble free kilometres... This morning I went to start the car and it was a no go, first few attempts the engine just stalled out, subsequent starting would result in idle for 5-seconds and then stall. Smoke was being emitted from the exhaust, appears to be unburnt fuel. It eventually started but smoked a bit during idle. The main fuel pump (I believe there are two?) was replaced around 8 months ago, so it doesn't have issue getting fuel.
I'm wondering if this may be an EGR issue? I had noticed that between the last few oil changes she had lost around quarter of a litre of oil over the normal service intervals, I dare say this is being consumed somewhere, maybe crankcase ventilation.
I took one of the hoses off the intercooler, the front one towards radiator and noticed some oil residue in the hose and some around the mouth of the intercooler, no doubt there is some inside the intercooler too. Not sure if this is anything to be alarmed about, I have read this does happen to some diesel engines with high kilometres and can be caused by oil entering the air intake pipes via crankcase ventilation, not sure if that applies to the 2.2L in the Sante Fe. Also grabbed a torch and had a look around the engine bay, while it's relatively clean I noticed some oil around the turbo intake piping.
Engine noise is a little clanky, I read in the EGR cleaning thread that this subsides considerably when the EGR is cleaned or replaced. Last oil change the engine was fairly quiet, but after around 2,500k's it's returned to being clanky.
Have recently had some stalls when driving around town, rough idling when pulling up and loss of power when cruising at 60kph. I have noticed this seems to occur at low speed and often after I stop accelerating.
There's a bit of vibration when the engine is idling, more so than normal, not sure whats causing this but I originally thought it was the idler pulley wheel bearings so had the entire assembly replaced, it appeared to fix the issue somewhat but it has returned in a fairly short time. One of the pulley wheel bearings was shot and was contributing noise. If I put the AC on the low vibration noise I hear increases, also when I turn the steering wheel, basically when the engine is under load from an auxiliary source! At 1800-2000rpm the low vibration (purring) noise is not present. I'm worried there could be an oil pump issue occurring here, it appears to be lower in the engine bay, I don't think it's a knock or major failure of the engine internals, the sound is more inline with an exhaust vibration, yet it isn't the exhaust.
If anyone has some ideas on the possible issues I'm experiencing please feel free to list them, just looking to be informed before I have my precious towed to the Hyundai dealer for further inspection.
Was hoping to get a little longer out of my faithful steed and hope this isn't the start of some very expensive repairs or time for retirement!
