hey guys i have this engine noise i would like you to hear but i can load audio here so if you would like to listen please send me your email address and ill send the file... ok as you may know i replace the lifter inmy car this is the second set and there is still noise like a bad lifter coming from the motor a idle but this noise is after a slight rpm riv up and as its coming back down in rpms theres a thump.. its loud enough to hear and feel in the motor as your riv up the rpms it only does it on the down side of the riv i think   its really hard to decribe what it sounds like be glad to send the file so you can listen.. can anyone give me ideas to the cause..

you could try emailing it to me rocketman[AT]werbatfik.com

is it a metallic noise? does it sound like lifters?

Are you still using your original head? If to you may have a blocked oil passage that is starving the lifters of oil. Another possibility, albeit unlikely, is that the lifter buckets are worn excessively and allowing too much oil to bypass the lifters and they're not pumping up.

Whats your oil pressure like? What shape is your oil pump in? What type of oil are you running?

ya know cheap gas or sometimes gas with ethanol in it can make it knock around a bit  

[Rocketman]

I'm having a hard time hearing what you're describing in the file you sent me... almost sounds like a rod knock? doesn't make sense if you've got full oil pressure. Did you mess with the bottom end? Inspect your thrust washers/bearings?

[bryanknight]

no i did not take out the crank or the piston but i did check them to see if there would lose and i did not get any play from the crank or the pistons  the sounds sounds like its right on top not lower and if it was a rod it would do it all the time right  not just on the down side of rpms  and i know what your talking about on the gas but its much more then gas here the only thing that has change are me putting the lifters in and cams since the last time i drove it because the the lifters went bad on the last time and the other noise and just can in the picture this time i am going to remove the cams again and check the lifters and then the springs and im going to put the cams in with out the lifters and see if i can move the cams and if the springs are good and lifters are good i am going to put a bullet in the motor and call it good..........

[bryanknight]

ok guys took the cams out and the lifters are primed, none of them give at all so thats good  so i took them out and put the cams back in, there is no play in the cams up and down but just a little in and out i think its in specs. i am going to build and jig tomorrow to check the spring tension book says 44lbs at 1.5  but i see nothing that could be causing this i took plugs out and took all the belts off and turned the crank by hand and i feel nothing lose dont mean much but i check all the oil rails they are good and pumping out great  


 does anything think that the trans could be doing that some how??  

 come on poeple with car knowledge!!!!  give ideas things to try im asking for help here.. i know many things but i always like others info!!!!!

My buddy had a similar issue with a haunted engine...turned out to be his flywheel to crank bolts. But it was a lot louder.

[bryanknight]

well as an up date to my on going problem sence all the knowledge on the form only two people seems to try to help me with a problem in my motor or had any idea of something to look in to. as i know many of you are building you motors and had no in put to a fellow xr2 owner.. i well be forced to take my motor completely apart again to look for the source of the noise.. Its really pisses me off that the lack of responce is and was so low with the amount of knowledge on here..If i get removed from this forum for my comments here so BE IT...

[CapriTypeR]

I'd love to chime in and help, but I don't have a clue!  I usually take my car to the mechanic when something goes wrong....or call Matt......

i wish i knew the problem ! i can replace parts that are easy to get to but when it comes to engine internals thats way out of my league. sorry that we could not be of more help.

[bryanknight]

sorry guys i just got a little hot about having to take my hole motor apart to see whats wrong and to day i did that i dont really see anything wrong maybe bad piston rods bearings or piston cylinder wall clearence but i take it to the shop monday  thinkin i am going just going to bore it and get that kit off ebay egle rods and wisco piston and get that out the way for awhile

[CapriTypeR]

No worries!!  It happens to the best of us!

[bryanknight]

does anyone have a low mileage head ?? thats should be like new vs my 109,000

[bryanknight]

and this is what it was!!! grrr but it did not fuck the bore up so new pistons and bearings and back on the road

[CapriTypeR]

All the ones I have are higher mileage. EXCEPT for the one that has appx 10 miles on it since it was rebuilt. But...i would need like $350 for it to break even.  If you are interested, let me know, and I can tell you exactly what was done to it.
