Hi guys! Ask naman sana ako ng advice sa inyo, i have a 96 vtec. I am experiencing high engine temperature readings. Usually, nasa gitna lang yung needle ng gauge, but now, umaabot sya ng 3/4. I checked the oil kung may whitish color sya, wala naman, does that mean ok pa yung cylinder gasket ko at walang leaks ng oil at water? i seldomly add any water, say about once a week using a 330ml bottled water container, sa reservoir pa ko nglalagay kasi un ang nbabawasan and not the radiator mismo.
I also noticed na tumataas sya ng temp everytime nag da-downshift ako to overtake, when climbing uphills, and when suddenly nagbreak ako coming from 80-90 or pataas pa,..

additional questions:
1.kapag barado ba ang simota air filter or marumi na, isa sya sa magiging cause?
2. Someone told me that Simota Big tubes will cause underpower rather than increase your cars' HP compared to that of short rams?
3. I dont see any oil mixing with water sa radiator ko. it means ok pa mga gaskets?

Thanks and more power Tsikot!
