Do bad hydraulic lifters cause low oil pressure?
Im getting engine ticking. The ticking seems to be coming from the upper end of the engine. Drove the car with the ticking for more than 4,000 miles like this. Ticking hasnt increased at all. Tried flushing the engine with engine oil about 3 times, thinner oil, synthetic...but no difference. There is also a knocking noise that you cant hear even with the hood open. You have to get your head really close to the engine and listen very carefully to hear it. The oil pressure was as factory spec about 2,000 miles ago but just a few days ago i hooked up a gauge and it is very low. Repair manual says it should be 53psi @1800rpm. But now its idling at 20psi (when engine warm, 40psi when not) and 40psi @ 2000rpm. So basically all i want to know now is...do bad lifters cause low oil pressure? Engine: 03 Buick s2 3800 V6
What are signs that your car needs a complete engine overhaul?
It depends what you mean by “complete engine overhaul”.For most modern vehicles, with just routine maintenance (and running on the correct grade of good quality fuel) the engine should comfortably last for the economic life of the vehicle and never need a true overhaul.However, I would say that if there are signs that the cylinder compression is starting to fall below specification then there’s a good chance that a major overhaul is necessary.In the old days when engines were much simpler it was not uncommon for people to overhaul engines. That might have involved a complete stripdown, and replacing bearing shells, replacing piston rings and regrinding valve seats etc. However, today the number of workshops offering such services has fallen, and labour charges have risen to much higher levels. For modern cars the complexity and congested nature of the average engine bay means that it’s usually uneconomic to do an “old school” overhaul.If you do have an old car, with more than 150,000 to 200,000 miles on the oddometer, and you want to completely overhaul the engine, it can still be done and it can be a lot of fun. However, you’ll need access good workshop facilities as well as time, money and patience. You’ll have to consider buying a complete set of gaskets, seals, bearings, possibly valve springs and piston rings. If the cylinder bores are appreciably worn you might need a lot more. Certainly think twice before committing to such a project, especially if you have to pay somebody else to do the work.
Lifter tick cause check engine light?
Im looking at a 3000gt which seems to have a lifter tick. Which the internet says is a common thing with these vehicles. They guy tells me the check engine light came on same time the lifter tick started...could just a lifter tick cause the check engine light to come on? if not you are saying there is possibly a bigger problem that has caused it? Thanks for your help. ( it doesnt sound like a bearing or knocking just the ticking...just wanna know if that can cause the light to come on )
How long can you drive with a lifter tick in your car?
i used thicker oil on my mustang 04/ 5-20 to 10-30 synthetic. it has 114k miles now but tick started around 95k and it comes and goes with temp change... but quieted down significantly. if you cant replace or clean lifters i suggest trying out the thicker oil. had an exhaust leak too and you can tell the difference by hearing sound from engine head or when you speed up from chassis... hey maybe you just might have both problems... exhaust leak isnt really an issue to make you run out and fix right away/ major concern i guess would be rusting. but you might want to check lifters within 25k miles (ball park figure if it doesnt sound too obnoxious after oil change) ps you can get away with thicker oil for older cars but just dont go over board with 10-40 on that camaro
Finally got the lifters replaced... ?
"Loosen up and build up oil" sounds like the mechanic has no idea as to why the ticking noise is still there or why it was there in the 1st place. Loose lifters will make more noise, not less. Oil (pressure) build up is almost instantaneous, not in 60 miles. Did you tell the mechanic to replace the lifters because of the ticking noise or did the mechanic tell you that the ticking noise was from the lifters? If you told the mechanic, he did what you told him to do. Maybe it wasn't the lifters at all. A high voltage leak in the plug wires will cause a ticking noise as the spark jumps to ground and you might not feel the engine missing or a code might not necessarily be set. When it's dark outside, start the engine and look all over the engine compartment for a blue spark that may be jumping from plug wires or somewhere in the high voltage system (coil, etc). It may make it easier to see if a TRUSTED friend in the driver's seat puts the car into gear. The extra load may make the sparking and arcing easier to notice. But without me looking and listening myself, I can't offer anything else. You can buy yourself a stethoscope (about $20-$30) and try to listen and isolate the source of the ticking noise. My ticking noise was caused by a cracked piston, but it was louder than a "tick" and became louder as the engine warmed up. Another car I owned had the high voltage problem - more noticeable when going up hill (engine loaded more).
Worn or Incorrectly Adjusted Rocker Arm(s).?
Does it run ok other than the blue smoke? I broke an intake rocker stud one time, pulled tons of oil through the piston rings into the combustion chamber, and smoked like a chimney. But not likely your case... It's far more likely you have a bad lifter than anything needs adjusted, as the hydraulic lifters used in your engine are a "set it and forget it" sort of setup...if they are making noise, SOMETHING has failed, whether it be the lifter, the rocker arm nut, etc. The blue smoke is oil, valve stem seal and/or worn guides will cause this. Likely the seal.
