orginally we thought my turbo was bad cuz the car smoked at boost now we've checked the turbo and it has no shaft play but a new problem has come about the car now has a rattle or slight knock sound coming from the head the oil is fine and we pulled the valve cover and checked everything topside pulled the plugs and check those they were also fine. does anyone have an idea as too what i should check for or has this been an issue for anyone before? motor is a stock sr20 with front mount on stock psi any feed back would be greatly appreciated thanks

the rattle might be the upper timing chain guide, i know that's a common problem with KA's... if not, with the oil issue you speak of, it may be your valves, and their guides...

 

did you check the blinker fluid?

 

^thats a honda issue. timing guide in the front of the head??, any noise when you rev it up???, possibly a lifter getting stuck???, how many qts of oil do you put in????

 

car has a fresh oil change oil has been checked and level is good timing chain cover was removed as my friend had one snap off on his ka but this is an sr and im thinkin it has to be stuck lifter or possibly a valve issue but i wanna get some feed back before we pull the head oh and ya noise get louder when rpms rise but doesnt get faster so its not in the bottom end

 

had a lifter stick on one of my sr's b4, sounds like the same as you have described. i used 1 quart of lucas oil stabilizer and it worked for me. i ran it for for a couple of days and then did a reg. synth. oil change. i would not advise leaving the lucas in there for 3000 miles tho. food for thought b4 you pull the head

 

Here's an idea. Let someone look at it who knows what they're talking about.

 

^how rude^

 

well id gladly let anyone who "KNOWS WHAT THERE TALKING ABOUT" take a look but there doesnt seem to be anyone who wants to help me out thus the reason im searching for answers on TR

 

Well if it was my engine and i heard a knocking noise i would kill each cylinder one by one to determine if it coming from a specific cylinder like mabye a rod knock. What RPM does the noise become present? I see you say the noise gets louder but not faster. Now that i would have to hear. The smoking issue could be due to excessive blowby and/or piss poor crankcase ventilation. Has a compression check and leak down check been done yet?
