LingLing Posted July 22, 2012 Share Posted July 22, 2012 Since I had this car, The 4age bluetop does have some tapping noise while it first start in cold, but when it gets warm it seems to be better. or maybe my exhaust and diff is so noisy I can't hear it. I have done bit research and found this might be the easiest way to treat it. http://rislone.co.nz/catalog/view/117-e ... ment-44100 Don't have the knowledge nor have the tools to replace the valve lifter yet. 1 Quote Link to comment Share on other sites More sharing options...

felixx Posted July 22, 2012 Share Posted July 22, 2012 If it takes a minute for the noise to disappear (or get less) old be an exhaust leak.. check the junction where the exhaust meets the manifold. If there is black sooty marks there, you have a leak. You could try mani seal putty. You may have more loose bolts, tighten the bolts on your manifold (and the ones on the flange that covers the junction of the manifold and exhaust pipe if you have a cast iron manifold, if you have extractors, they are probably welded to the pipe) Just tighten them gently, toyota didnt use TRD bolts when attaching manifolds so they could snap Quote Link to comment Share on other sites More sharing options...
LingLing Posted July 22, 2012 Author Share Posted July 22, 2012 yeh, that could be a problem. I know in fact I miss one of the exhaust bolt. However, I have noticed the tapping before I changed the exhaust system. Quote Link to comment Share on other sites More sharing options...
felixx Posted July 22, 2012 Share Posted July 22, 2012 that will be some of your problem.. replace the bolt. Did you use new gaskets? Quote Link to comment Share on other sites More sharing options...
Dell'orto Posted July 22, 2012 Share Posted July 22, 2012 They're solid lifters, so that flush wont do bugger all. Quote Link to comment Share on other sites More sharing options...
LingLing Posted July 22, 2012 Author Share Posted July 22, 2012 that will be some of your problem.. replace the bolt.Did you use new gaskets? No, didn't use new gaskets either. they're piece of metal like gasket, and no damage on them, why should I need to replace it? solid lifters, so what else could cause the noise?

felixx Posted July 22, 2012 Share Posted July 22, 2012 you only need a small leak to make the noise. Go slip a bolt into the missing hole and do it up tight 90% certain the noise will go, but I shall shut up now incase I offend anyone Quote Link to comment Share on other sites More sharing options...

LingLing Posted July 22, 2012 Author Share Posted July 22, 2012 From the engine, or some part of the engine. shell hx7 10w40 http://www.shell.com/home/content/produ ... x_hx7/hx7/ Quote Link to comment Share on other sites More sharing options...

BlownCorona Posted July 23, 2012 Share Posted July 23, 2012 my 20v 4age makes a bit of a tap when its cold, but im not really sure what it is. could very likley be the exhuast manifold leak as felix described, need to check that out. was also wondering if it could be the injectors as i read somewhere they they can be a bit noisey, is that even possible? also solid lifters = cam right onto the valve/follower? because thats what i have. edit: might actaully be very very mild vvt pully tick, wont be an issue on your 16v version Quote Link to comment Share on other sites More sharing options...
Steelies Posted July 23, 2012 Share Posted July 23, 2012 i also get a bit of clickity clickity from my bluetop. it's a bit tired these days Quote Link to comment Share on other sites More sharing options...
LingLing Posted July 23, 2012 Author Share Posted July 23, 2012 I thought 20v injectors are very robust. the blue top ones are bit noise. I don't know but doesn't sound like them. will get screwdriver attach to my ears to hear the noise. Quote Link to comment Share on other sites More sharing options...
